Hello Daniel, I can certainly empathise with the feelings of anxiety that come from submitting for critique. It is clear that you’ve put a lot of effort into your work, and by and large you’ve done a good job. There are a few points to discuss which should help you get a bit more out of these exercises in future.

Starting with your organic intersections these are working pretty well. Your forms have a good sense of weight to them, as you allow them to sump over one another in three dimensions, paying attention to how gravity pulls the forms down into positions where they feel stable and supported. Your application of cast shadows shows a good understanding of how your piles sit in 3D space, and help to clarify the relationships between your forms.

Aim to stick to simple sausage forms for this exercise, as simpler forms are easier to convey as solid. You usually do this well, with just a couple of wobbly or deflated forms (like the one at the far right of this pile which start to feel a little flatter.

This isn’t currently stressed in the exercise instructions, but as a bit of a bonus, try to draw through and complete your forms wherever possible as shown in blue here instead of cutting some of them off where they overlap. This will push you into thinking through how the whole form sits in space, and help you to get even more out of the exercise.

Moving on to your animal constructions, there’s quite a lot here that’s coming along very well. You do a great job of starting with simple solid forms, and usually build things up piece by piece, without attempting to add more complexity than can be supported by the existing structures at any given stage. Your application of additional masses shows that you’re thinking about how to attach these new pieces to the construction “in 3D” and you’re clearly making careful and frequent observations of your reference images.

One thing to keep in mind for these constructions, is that you should strive to only take actions in 3D, by constructing complete new forms with their own fully-enclosed silhouettes whenever you want to add to the construction or alter something. Right now there’s a fair bit of hopping back and forth between taking actions in 2D and 3D, often enough to suggest that you might not always be consciously distinguishing between the two.

For example if you look here you’ll see I’ve used blue to trace over an example of extending the silhouette of the construction with a one-off line, and highlighted the extended areas. But these blue areas exist only in two dimensions - there are no clearly defining elements that help the viewer (or you, for that matter) to understand how it is meant to relate to the other 3D elements at play. Thus, it reminds us that we're drawing something flat and two dimensional, and in so doing, reinforces that fact to you as you construct it. Creating believable, solid, three dimensional constructions despite drawing on a flat page requires us to first and foremost convince ourselves of this illusion, this lie we're telling, as discussed here back in Lesson 2. The more our approach reinforces the illusion, the more we make new marks that reinforce it even further. The more our marks break the illusion, the more marks we make that then further break the illusion, for us and for everyone else.

While in this course we're doing everything very explicitly, it's to create such a solid belief and understanding of how the things we draw exist in 3D space, that when we draw them more loosely with sketching and other less explicit approaches, we can still produce marks that fall in line with the idea that this thing we're drawing exists in 3D.

These actions in 2D occur on the majority of the legs in your submission (highlighted with blue here), and here I think it is best to paste in the advice for legs from your previous critique:

It's not uncommon for students to be aware of the sausage method as introduced here, but to decide that the legs they're looking at don't seem to look like a chain of sausages, so they use some other strategy.

The key to keep in mind here is that the sausage method is not about capturing the legs precisely as they are- it is about laying in the base structure or armature that captures that captures both the solidity and gestural flow of the limb in equal measure, where the majority of other techniques lean too far to one side, either looking solid and stiff or gestural but flat. Once in place, we can then build on top of this base structure with more additional forms as shown in these examples here, and here. This tactic can be used extensively to build up the specific complexity of each particular leg, as shown in this ant leg demo. I'll also share this dog leg demo as an example of how to apply the sausage method to animal legs as we would like you to stick with the sausage method as closely as you can throughout lesson 5

It appears that you may have had some difficulty implementing the sausage method of leg construction, and I would suggest going through the donkey construction from the informal demos page, which goes over how to apply the method step by step in some detail. Here is another example drawn over the front leg of one of your constructions. As I’m not seeing the method being used in your submission, I will be asking for some minor revisions for you to demonstrate that you’ve understood the technique.

Moving down to feet, I'd like you to take a look at these notes on foot construction where Uncomfortable shows how to introduce structure to the foot using a boxy form. By that I mean a form whose corners are defined in such a way that they imply the distinction between different planes within its silhouette, without necessarily having to define the edges themselves, to lay down a structure that reads as solid and three dimensional. Then we can use similarly boxy forms to attach toes. Please try using this strategy for constructing feet in future.

So, one of the main tools we introduce in lesson 5 to help students build up their constructions in 3D (instead of adding one-off lines or flat partial shapes) is additional masses. I’m pleased to see that you’ve been experimenting with additional masses quite a bit, and by and large you do a great job of wrapping them around the basic structures of the torso convincingly. I do notice that (as with the masses traced over with red and purple here) sometimes you’ll cut additional masses off where they overlap with one another, but this is not correct. In situations where you've got two masses overlapping one another, remember that these are 3D forms - that means that when you drop a new form on top of another one, it should wrap around the existing mass in 3D space, just like any other part of the construction that you’ve already drawn.

One thing that helps with the shape here is to think about how the mass would behave when existing first in the void of empty space, on its own. It all comes down to the silhouette of the mass- here, with nothing else to touch it, our mass would exist like a soft ball of meat or clay, made up only of outward curves. A simple circle for a silhouette.

Then, as it presses against an existing structure, the silhouette starts to get more complex. It forms inward curves wherever it makes contact, responding directly to the forms that are present. The silhouette is never random, of course- always changing in response to clear, defined structure. You can see this demonstrated in this diagram.

So, here I’ve applied this to some of the masses on your wolf. Completing them where they overlap so we can more clearly define 3D relationships between them, as well as replacing the flat 2D extension under the belly with some additional masses.

Another thing to keep in mind with additional masses (or any form) is that additional contour lines as introduced in the sausage forms suffer from diminishing returns, where the first one you add may be quite helpful in clarifying how the form sits in space, but the second much less so, and the third (and fourth etc) will be largely redundant. While adding contour lines that don’t contribute isn’t a big deal, they can sometimes lead to people investing less effort into careful design of the mass, with the idea that additional contour lines can be used to “fix” the construction and make it more 3D, when they don’t actually help fix the underlying issue, which is a lack of a clear relationship between the forms, or individual forms that try to achieve too much in one step and are overly complex. So before you draw a contour line as part of a construction - or really, before you draw any line - think about what it is meant to accomplish as part of your drawing. If it isn't going to be contributing much, or if that task can be done better with a different mark (or is already being accomplished by another), don't draw it.

The next thing I wanted to talk about is head construction. Lesson 5 has a lot of different strategies for constructing heads, between the various demos. This is due to how the course had developed over time, and how Uncomfortable is finding new, more effective ways for students to tackle certain problems. So not all the approaches shown are equal, but they do have their uses. As it stands, as explained at the top of the tiger demo page (here), the current approach that is the most generally useful, as well as the most meaningful in terms of these drawings all being exercises in spatial reasoning, is what you'll find here in this informal head demo.

There are a few key points to this approach:

  • The specific shape of the eye sockets- the specific pentagonal (5-sided) shape allows for a nice wedge in which the muzzle can fit in between the sockets, as well as a flat edge across which we can lay the forehead area.

  • This approach focuses heavily on everything fitting together- no arbitrary gaps or floating elements. This allows us to ensure all of the different pieces feel grounded against one another, like a three dimensional puzzle.

  • We have to be mindful of how the marks we make are cuts along the curving surface of the cranial ball- working in individual strokes like this (rather than say, drawing the eye socket with an ellipse) helps a lot in reinforcing this idea of engaging with a 3D structure.

Try your best to employ this method when doing constructional drawing exercises using animals in the future, as closely as you can. Sometimes it seems like it's not a good fit for certain heads, but as shown in the rhino head demo just beneath it on the same page, it can be adapted to work for a wide array of animals.

The last point to mention is texture and detail. I really like how you approached the texture on your tortoise construction. Here I can see you were leveraging the shadows cast by the scales, rather than explicitly outlining all of the scales themselves, and this has allowed you to control the density of detail. This is excellent use of the methodology introduced in the texture section of lesson 2, well done!

On the zebra and leopard it looks like you got distracted by the colour patterns, but the fur has the same texture, whether it is part of a black stripe, or a white stripe. What we're doing in this course can be broken into two distinct sections - construction and texture - and they both focus on the same concept. With construction we're communicating to the viewer what they need to know to understand how they might manipulate this object with their hands, were it in front of them. With texture, we're communicating to the viewer what they need to know to understand what it'd feel like to run their fingers over the object's various surfaces. Both of these focus on communicating three dimensional information. Both sections have specific jobs to accomplish, and none of it has to do with making the drawing look nice. I understand that it is quite possible that you took to filling in stripes and spots with black based on Uncomfortable filling in some tiger stripes in the lesson intro video. The instructions on texture that are the most up to date, and also the most helpful in terms of all these drawings being exercises in spatial reasoning, are what you’ll find in the texture section of lesson 2, in particular, going through the steps in these reminders should ensure you stay on the right track.

All right, I think that should cover it. Overall your constructions are coming along well, although I am going to ask for some minor revisions. Please pay close attention to sticking to the specific requirements of the sausage method of leg construction, and make every effort to give each form you add to your constructions its own complete silhouette.

Please complete 2 pages of quadruped constructions.

Hi DIO,

Thanks so much for the detailed feedback. You are awesome and I can see you put lots of efforts into these and I learn A LOT. so I really really appreciate these.

However, I would like to note that for the specific case that I am being asked to review this submission (the legs) I can't help but feel that I have received mixed messages, since I really thought I was following the up-to-date instructions.

For example, when I go to the page of lesson 5, I see no warning stating that the video may be outdated at the top of the page (screenshot), and that I need to follow the legs instructions provided somewhere else.

https://drawabox.s3.us-east-1.amazonaws.com/user_uploads/CT6XFFR_anwqct8s.jpg

As such, when I click on that video, (which now I have realized is from 9 years ago), there's an explicit moment where Uncomfortable states that the legs go a bit 2D and he breaks his own rules there. https://drawabox.s3.us-east-1.amazonaws.com/user_uploads/CT6XFFR_6qr7kqjh.jpg

I do remember, at that moment, feeling surprised, but then I thought that perhaps insects worked better with sausages, but animals should be approach differently (like in the video).

Indeed, the instructions on the page show the dog being drawn with the sausage approach (which I was already aware from lesson 4). However, because the limbs section in the text format is really not that detailed (e.g., explicitly saying that we should be using the sausage approach), I somehow assumed that the video (which is more detailed about legs), should be followed for this lesson (wrong assumption from my part as I have learned now).

I guess all I wanted to say is: (i) I really tried to follow your feedback you gave me back in lesson 4 (i.e., to follow instructions strictly, and (ii) perhaps it would be really helpful to put a warning at the top of that page saying that the approach in the video for the legs is outdated, and that the sausage strategy (which we learned in Lesson 4, should be used instead). Not sure if this could be communicated to uncomfortable.

Regardless, I am very thankful to your feedback, and I will do the revision requested and upload the images on here. Please do not consider this one as my submission. I just wanted to give a wee feedback to the course.

Hello DIO,

Attached is the requested revision

I tried to better apply:

1 - Sausage method + construction for the legs

2 - Use the boxy shape as a construction foundation for the paws.

3 - Draw the entire shapes when adding them (as opposed to drawing 2d shapes).

Hopefully these ones came out better for the purpose of thes exercises. Do let me know.

Best wishes,

Daniel

Hi Daniel, thank you for completing these additional pages as requested.

Nice work, you’re taking actions in 3D by constructing complete new forms when you want to build up your constructions, and the improvement is most prominent in the legs, where you’re demonstrating plenty of ability with laying down chains of simple sausage forms for your armatures. I’ll be marking this as complete, but while I’m here I have a few notes for your (edit) you to keep in mind, which I’ve numbered on one of your pages here.

1- When working on organic constructions in this course, resist the temptation to cut back inside the silhouettes of forms you have already drawn, as you did with the section marked with red hatching along the hind leg. This will undermine the solidity of that form and remind you that the drawing is flat. We’ll be introducing correct subtractive construction with the inorganic constructions in lessons 6 and 7.

2- You’re constructing with 3D forms most of the time, but there are still a few areas where you’d made a quick addition with a one-off line or partial shape. I think that you do understand how to build things up in 3D, and it is a matter of taking your time, being patient and mindful of every step you take, and completing each form before moving onto the next.

3- I wanted to call out that these additional masses along the neck were well designed, and wrap around the underlying structures convincingly, nicely done.

4- When using the sausage method of leg construction, once the sausages are in place we use one contour line at each joint to show how the forms penetrate one another and establish a 3D relationship between them- just like the contour lines introduced in the form intersections exercise from lesson 2. I’ve added them to your construction in red.

5- I noticed with the masses that I’d traced over with purple, that you’d introduced a sharp corner at an offset, so it occurs at a random point on the smooth underlying sausage form. Take a look at these notes showing how moving the corner to the edge of the underlying form allows the mass to wrap around it more convincingly. While additional masses should transition smoothly between curves where the underlying form is smooth and rounded, there are cases where we can include more complexity in masses’ silhouettes. A good example of this would be the bulky shoulder and thigh masses, where the top of the legs join the torso. We can press additional masses against these protruding forms, which helps to anchor them more securely to the torso. The more interlocked they are, the more spatial relationships we define between the masses, the more solid and grounded everything appears.

You’ve made a great start with using additional masses to build upon your leg sausage forms to develop a characteristic representation of the leg in question. As a bit of a bonus I’d like to discuss a way we can push the method still further. A lot of these additions focus primarily on forms that actually impact the silhouette of the overall leg, but there's value in exploring the forms that exist "internally" within that silhouette- like the missing puzzle piece that helps to further ground and define the ones that create the bumps along the silhouette's edge. Here is an example of what I mean, on another student's work. Uncomfortable has used green to block out masses along the leg there, and included one fitting between them all, even though it doesn't influence the silhouette. This way of thinking- about the inside of your structures, and fleshing out information that isn't just noticeable from one angle, but really exploring the construction in its entirety, will help you yet further push the value of these constructional exercises as puzzles.

With regards to your other response, I know it can be really frustrating to be asked to complete revisions. Keep in mind that while leg construction was the most consistent issue that I highlighted, there were at least 5 other points/recommendations in my initial critique, so there was plenty of additional advice to sink your teeth into, and those 2 additional pages would be well worth your time and effort.

As our overhaul of the lesson video/demo material progresses slowly (during which we're updating things to reflect methodologies we think better capture the goal of the course - for example, constructing legs using sausages instead of the way shown in the video you linked), we share any additional demos/methodologies/etc. with students on the official critique via the feedback they're provided, but it does fall to the student to do whatever they deem necessary to apply that information.

So- back in lesson 4, I did my best to make sure that you were aware that the sausage method should be used throughout lesson 5, by flagging it with bold text, and issuing a reminder in the last paragraph of your critique to refer back to it and apply those points to your animal constructions. I will forward your message to Uncomfortable to see if he thinks it is a good idea to add a disclaimer to the lesson intro video, similar to the one at the top of the tiger head demo.

Feel free to move onto the 250 cylinder challenge, which is a prerequisite for lesson 6. Keep up the good work.

Next Steps:

cylinder challenge

This critique marks this lesson as complete.

Thanks so much, DIO. Your feedback is always amazing! I'll work on all the things you pointed out.

Cheers,

Steven Zapata's Secrets of Shading

Some of you will have noticed that Drawabox doesn't teach shading at all. Rather, we focus on the understanding of the spatial relationships between the form we're drawing, which feeds into how one might go about applying shading. When it comes time to learn about shading though, you're going to want to learn it from Steven Zapata, hands down.
