I focused mostly on construction, so I didn't texture many of them. The improvement from the first to the last insect is noticeable. I think I might have lowered the transparency of the construction a bit too much.

At first, I started this lesson on the rough side, but then, as I got into the flow of constructing insects, it became much much easier. I found myself spending hours and hours just diving deep into the construction. I felt like I was about to finish a game and disregarded time, lol. I Still have some perspective issues, e.g. the scorpion tail looks off, but overall I think I did a decent job.

Some of my drawings have sausages instead of proper limbs. This is because I failed to realize that I should add the extra masses after drawing the sausage.

Anyways, please leave a critique if you have the time.

Starting with your organic forms, these are generally looking quite good. There are a couple of things i want to point out here:

  • Remember that were aiming to stick to the characteristics of simple sausages. This means ends that are equal in size, circular in shape, connected by a tube of consistent width. The midsections are okay, but their ends are differing in size, some even stretch out a little bit.

  • In your contour curves, you tend to stick to the same degree throughout the length of the sausage form. In your contour ellipses, you're shifting them (which is correct), but it does appear somewhat inconsistent, which suggests that you're not entirely sure how to handle these. This is explained in the ellipses video from Lesson 1 so go give it a watch. Basically, the width of the ellipse depends on its placement in space relative to the viewer, assuming that there's no rotation happening.

Moving onto your insect constructions, here your approach became more consistent than before. Some of the problems from the previous lesson carried over as a result. As I've said before, these are of course exercises, so the focus isn't on how the end result comes out. The goal is to clearly define how the forms sit in relation to one another, using tools to manipulate forms in 3d space.

The first thing is that the problem with starting with faint lines, then tracing over it with darker lines became much more prevalent here. Remember what i said before, this approach should be avoided as it treats the previous lines as if though they weren't there. You're essentially replacing it with a purposefully thicker line which diminishes the overall effectiveness of the constructional principles as a whole.

Because we're drawing on a flat piece of paper, we have a lot of freedom to make whichever marks we choose - it just so happens that the majority of those marks will contradict the illusion you're trying to create and remind the viewer that they're just looking at a series of lines on a flat piece of paper. In order to avoid this and stick only to the marks that reinforce the illusion we're creating, we can force ourselves to adhere to certain rules as we build up our constructions. Rules that respect the solidity of our construction.

For example, once you put down a form, do not alter the silhouette. The silhouette is just a shape that represents the form we're drawing, but its connection to that form is entirely based on its current shape. If you change that shape, you wont alter the the form it represents, you'll just break the connection. This example shows us what happens when we cut back into the silhouette of a form.

There are a couple of examples of this happening in your drawings:

  • On this mantis shrimp, you started with a larger form for the abdomen but then redrew it with darker lines and cut back into it.

  • Same thing happened on this ant where you drew the mass for the thorax, but then cut back into the smaller masses.

There's a pretty high risk of running into this trap generally, even by just tracing back over an existing line because of any additional complexity you might add by wobbling/hesitating as you draw that mark. There's also some similar issues which we might run into by extending the silhouette, like when we add flat or partial shapes to an existing form like the little spikes on the green mantis' arms.

There are other times where it appears like you're adding flat shapes because of how you're tracing over your drawings. Most notably, the abdomen of this damselfly.

Instead, if we want to change what's already there, we should introduce other three dimensional forms and establish the relationships between the additional masses either by defining the intersection with contour lines (as mentioned in lesson 2's form intersections) or by having them wrap around one another, where the presence of one form displaces the other. You can see this in practice in this beetle horn demo and this ant head demo.

I also recommend the first two informal demos, the shrimp and the lobster, as they show how you should think about wrapping these plate-like forms around the insect abdomen area.

Notice how in both of those examples, the instructor doesn't hide anything. Every form is drawn purposefully and confidently. They're not aiming to be perfect reproductions of the reference image. The reference itself is just a source of information that helps figure out what forms to construct and how to arrange them in believable ways.

Moving onto the topic of legs, I noticed you seemed to employ different strategies here. While not uncommon for students to be aware about using the sausage method, but instead they decide not to adhere to them because the legs they're looking at don't actually look like a chain of sausages to them.

The sausage method as a base structure allows us to capture the solidity with the gestural nature of legs. Once in place, we can lay in additional masses to convey the complexities as shown here, here, this ant's leg, and even in this dog's leg. This'll become relevant coming into the next lesson where we stack forms on top of one another (as per the organic intersections exercise from Lesson 2).

Overall, it seems like you're perfectly capable but I still want to assign some revisions below to demonstrate your understanding of the points and demonstrations shared above. If you've already started drawing animals from Lesson 5, it would be a good idea to toss those aside and start over. Focus on these points before moving forward. It's your choice to make on whatever you think is best at the end of the day.

Good evening,

Again, thank you for leaving these critiques. They are incredibly helpful.

On your first point. I had some difficulty trying to do the sausages in one motion, that's why I started practicing curves, lines, ellipses for at least 30 minutes before drawing. On your second point. you are correct. I find perspective somewhat hard and I feel like I under-perform when it comes to it. I'll keep on practicing though.

Moving onto your insect constructions, here your approach became more consistent than before. Some of the problems from the previous lesson carried over as a result.

The first thing is that the problem with starting with faint lines, then tracing over it with darker lines became much more prevalent here

This is completely my fault, I lost sight of the core focus of these lessons and submitted things I shouldn't have. I don't start out with faint lines, I simply lower the transparency after finishing the construction. This is not excusable though, not part of the exercise.

You're essentially replacing it with a purposefully thicker line which diminishes the overall effectiveness of the constructional principles as a whole.

I do find this part confusing though. During the organic intersections exercise, uncomfortable mentions that we should add line weight to emphasize what is in front of what. I guess my logic was kind of like this, in order from thicker to thinner line: Outer lines > inner lines > detail. Should I avoid doing this during the rest of these lessons? or drawing in general?

For example, once you put down a form, do not alter the silhouette. The silhouette is just a shape that represents the form we're drawing, but its connection to that form is entirely based on its current shape.

I'm also slightly confused by this. Adding new masses will inevitably alter the silhouette. If this is referring to cutting back into it and adding flat shapes like you mentioned I did with a few of my drawings, then I agree. I made a few mistakes there. I'll keep that in mind and avoid that at all costs.

I also recommend the first two informal demos, the shrimp and the lobster, as they show how you should think about wrapping these plate-like forms around the insect abdomen area.

I gave them a watch, thanks.

Moving onto the topic of legs, I noticed you seemed to employ different strategies here. While not uncommon for students to be aware about using the sausage method, but instead they decide not to adhere to them because the legs they're looking at don't actually look like a chain of sausages to them.

At one point uncomfortable says that I should always pick the form that better suits the subject. I think it was during the scorpion video. He also mentions something similar when constructing the louse's antennae. I guess I got those mixed up. So I should always use sausages for the limbs, and pick the best form for everything else?

Since I took a break I decided to do a quick recap of the lessons. I also finished the drawings you requested, this time without the transparency stuff. No texture, just plain construction, trying my best to do it like im supposed to. You can find them here:https://imgur.com/a/R5s2v5Q.

Unfortuantely, I submitted the next lesson without seeing your critiques. However, I'm gonna take your advice and I won't move on until I get that one critiqued.

Once again, thank you very much for taking your time writing these thorough critiques.

Sorry for the late reply. The website logged me out and just barely realized why i haven't been getting any notifications this whole time.

Alrighty so, I've looked through your work and it looks like you've pretty much nailed the exercises. My biggest issue beforehand was tracing back over the construction lines but it looks like you gotten that taken care of.

About the lineweight, yes its a tool used to clarify overlaps and that's it. Its not something that's used loosely for anything else. I mostly mention it because in the demos all the construction lines are there. There's no attempt to hide anything from the viewer whatsoever. In your original submission, the faint lines gave the impression that they weren't really there and that's where the problem was.

Altering the silhouette means changing the original form into something else. What we want to do is introduce other complete 3 dimensional forms on top of one another to create the illusion. Cutting into the form results in undermining the solidity of those forms.

When drawing the legs, we use the sausage forms since its easier to capture the solidity while keeping the gestural flow. Then you can come back and add the other masses later.

That's about it. Overall, your work is looking pretty solid but there is still much left ahead of you. Remember that these lessons are just exercises and were not aiming to draw plants, insects, or anything the lesson pertains to. All we've been learning thus far is to stack forms on top of other forms and establish their relationships in 3d space with insects being the subject matter. With that said, thank you for taking the time to do the revisions. Feel free to move onto the next lesson if you'd like.

Pentel Pocket Brush Pen

Pentel Pocket Brush Pen

This is a remarkable little pen. Technically speaking, any brush pen of reasonable quality will do, but I'm especially fond of this one. It's incredibly difficult to draw with (especially at first) due to how much your stroke varies based on how much pressure you apply, and how you use it - but at the same time despite this frustration, it's also incredibly fun.

Moreover, due to the challenge of its use, it teaches you a lot about the nuances of one's stroke. These are the kinds of skills that one can carry over to standard felt tip pens, as well as to digital media. Really great for doodling and just enjoying yourself.
