This exercise has been sitting a while on my drawer ever since I have finished it, but I'll try to give some of my thoughts that I remember when doing this.

  • Arrows: It is probaby me, but I don't know why I felt that it felt a bit natural with not that many hatching. I tried doing something a bit wild with how the arrows move and as you can see, some of them ended up with a weird direction.

-Contour Ellipses and Curves: I combined the Ellipses with one of the dissections. Overall, I think I managed to grasp the 3d concept better on the ellipses compared to just the curve. Looking back, I think some of the contours for the curves looked a bit samey between each other, I should try to bend it more according its location (more bended the further it strays from the center)

-Texture Analysis: I'm not quite sure if I did it properly, feel like what I'm doing is just putting more black on the left side compared to the right. It feels fun doing it and I would probably love doing it again another time, though very time consuming and sometime some of the pattern are stressful to draw. Personally not really confident with the brain coral one.

-Dissection: Some of the texture I picked might be a bit, out there. I think I chosen vegetable soup and even pizza. Maybe I'm just hungry, but I have a lot of difficulty on drawing patters that are smooth. Wood that has been surface finished or like aluminium looked like they don't have any texture, just colors that flow together.

Form Intersection: I think the hardest part in this exercise is to determine which surface do you hatch. You can see in the first drawing (the one with all squares) that I wasn't confident in drawing the hatching, resulting in not many hatch. Though I get a bit more comfortable with the different forms.

Organic Intersection: The way I do this was draw one/two form then put in some shadows. Some of the forms are intersected multiple time that sometime I accidently finished the shadow for a specific sausage only to realize that the shadow is wrong because I put another sausage in front of it.

Well, I hope to hear your opinion. Thanks :D

Hey, I'll be looking at your submission.

Organic Arrows: On the first page, you seemed to be afraid to overlap the edges, but this got better with the second page. In future warm-ups, work on getting more confident with overlapping. This sells the idea of a drawing being in 3D. Also, hatching tends to be inconsistent on some arrows. One thing to remember is that you should hatch on the part of the arrow that is being overlapped. If there is no overlap, or the part is doing the overlapping, it should not be hatched.

Organic Forms with Contours: While I can see the ellipses on the dissections exercise, I would appreciate seeing this without all the textures to better appreciate the ellipses. If you have that picture before doing dissections, please submit that. If not, I would recommend doing another page of contour forms with ellipses. For the page with contour lines, the contour lines look mostly fine, as they hook around, but you should make sure that they vary as you go through the sausage form. Most of these contour lines have the same degree. Furthermore, you do not want to use a lot of contour lines for a sausage. Depending on size, you should use three max for a small sausage and five (maybe six) for a big sausage. What happens is that not only do you not have the space to vary the degrees of the contour lines, but you also ruin the illusion of 3D when you "overemphasize" the curviness of the sausage. You did a good job in showing that the contour changes direction when the sausage bends, so keep that up. However, I would recommend doing another page of organic forms with contour lines and focusing on conveying the form with 3-5 contour lines.

Texture Analysis: You did really well in capturing shadows with the implicit method. And your transition into light looks remarkable. One thing to keep in mind is to make sure the transition from dark to texture is much smoother. You don't want a stark dark to light; it should blend in.

Dissections: For most of these textures, you managed to capture implicit shadows well, too. Some that I really liked were the tentacles, the coconut, and the ice cream. There were some textures that look less implicit and more explicit, basically you drawing what was there. One good example is the pizza texture. This one is a little difficult because in order to convey the texture, you have to draw the food that is there. However, it is still possible. You can convey the texture by focusing on the overlapping pepperonis or toppings. You could also do a cheese pizza texture by focusing on the broiled/brown spots on the pizza. One other suggestion is focusing on one slice instead of the whole pizza. Or maybe you can focus on the crust, as that might be easier to convey. Another example is the fur texture, which is also a difficult texture. Uncomfortable gets into this in a future lesson, but fur texture is not just zigzag lines or spikes. It is important to draw each tuft like it is unique, because it is. It is similar to the grass texture. Now, since you are practicing implicit shadows, this can be a little difficult, but keep in mind if you are drawing animals in the future that drawing the fur texture depends on drawing a tuft singly.

Form Intersections: Good intersections overall. If you decide to do this as warm up in the future, feel free to push the intersections more and allow the forms to "interact" more by pushing them closer. This challenges your mind to figure out how they interact, but it is a fun challenge. You tend to use a lot of dramatic foreshortening in this exercise. Be cautious of this in future warm-ups, because it can be jarring to have several dramatic foreshortened forms intersection each other with shallow foreshortened forms also in the mix. It would be better to focus more on shallow foreshortening in all these forms for future warm-ups. Finally, hatching shouldn't be used to convey intersections; it is used to show which side of the plane is facing us. Also, it is optional, so you don't have to hatch if you don't want to. Just keep this in mind for future exercises that involve hatching.

Organic Intersections: The sausages and contour lines look fine here. It does seem that you struggle to figure out where to place shadows; there are even some sausages that lack shadow when they should have it. As a rule of thumb, any sausages on the bottom should have a cast shadow; this establishes what surface they are on and forms the basic for the structure itself. As for the other sausages, it is best to place the sausages first before placing the shadow. This forces your brain to figure out how the shadows will interact with the surfaces. They shouldn't just be straight and stiff; they should conform to the curved surface if the shadow is falling on a curved surface. In addition to that, it would be best to limit yourself to 6-8 sausages per page so you can better track how the sausages fall on each other and how their shadows interact. I would recommend doing one more page of organic intersections and limit the number of sausages to 6-8. Focus on how the shadows should fall on the surfaces for each form. Sometimes, they might not have much of a shadow.

Overall, keep up the good work. I'll place what you need to redo in the revisions section. Once again, it is one page of organic forms with ellipses, one page of organic forms with contour lines, and one page of organic intersections.

Next Steps:

One page of organic forms with ellipses

One page of organic forms with contour lines

One page of organic intersections

Hi,

First of all I would like to thank you for your critique :D

For the arrows, I did some of hatching on non overlapping part because I thought I would convey the non overlapping part as some sort of cliff, where the side would be higher. Thanks for the feedback and I'll keep that in mind on Part 3.

Like you said, I think the one thing I really needs to practice is the cast shadow. I was surprised that you liked the texture analysis, even though I thought I'm gonna fail that one haha. I'm agree with your feedback regarding the fur texture. I'll try to practice about it in the future! Sometime your brain just overgeneralize the tuft and then I ended up following it.

I'll try to warm up by doing more shallow foreshortertning. I kept getting afraid that if I don't have an extreme angle, it might not be good enough or that I wouldn't learn that much. But now I understand :D

I took your advise on the organic intersection by doing the sausage first followed by the shadow. It helped me a lot and I believe reduced the amount of error I made on the revision. So thank you! Also I realised in some of the revision that some of my sausage wasn't that confident, sorry about that!

I have reduced the amount of contours for the organic form, though I made around 5 contours/ellipses per sausage. I thought the small sausage would be fine? But if you think I should do another revision for it, please just ask! It's partly because I thought the example had around the same contours and well, I accidently misread your feedback after I finished making the revision.

Most of the time, I am conflicted whether to add too much detail or too little. I think that's my problem in general, putting it too much detail because I'm afraid of well, blank detail that our brains can fill in.

Nicely done on all of these. I think you did fine on the number of contour lines and ellipses per sausage. Just keep in mind that as you continue to practice, you may find yourself using less contour lines or ellipses to enforce 3D forms.

As for the organic intersections, it looks very good. I can tell that you focused on how the shadows fall of each other. There are a few that still need a little work. The one on the bottom left has its shadow more attached to it when it should be more on the floor. And the middle one also could use a cast shadow on the floor.

All that being said, great improvement. I'm fine passing you for this lesson. Keep on practicing these in warm ups.

Next Steps:

Continue to the next lesson.

Let's be real here for a second: fineliners can get pricey. It varies from brand to brand, store to store, and country to country, but good fineliners like the Staedtler Pigment Liner (my personal brand favourite) can cost an arm and a leg. I remember finding them being sold individually at a Michael's for $4-$5 each. That's highway robbery right there.

Now, we're not a big company ourselves or anything, but we have been in a position to periodically import large batches of pens that we've sourced ourselves - using the wholesale route to keep costs down, and then to split the savings between getting pens to you for cheaper, and setting some aside to one day produce our own.

These pens are each hand-tested (on a little card we include in the package) to avoid sending out any duds (another problem with pens sold in stores). We also checked out a handful of different options before settling on this supplier - mainly looking for pens that were as close to the Staedtler Pigment Liner. If I'm being honest, I think these might even perform a little better, at least for our use case in this course.

We've also tested their longevity. We've found that if we're reasonably gentle with them, we can get through all of Lesson 1, and halfway through the box challenge. We actually had ScyllaStew test them while recording realtime videos of her working through the lesson work, which you can check out here, along with a variety of reviews of other brands.

Now, I will say this - we're only really in a position to make this an attractive offer for those in the continental United States (where we can offer shipping for free). We do ship internationally, but between the shipping prices and shipping times, it's probably not the best offer you can find - though this may depend. We also straight up can't ship to the UK, thanks to some fairly new restrictions they've put into place relating to their Brexit transition. I know that's a bummer - I'm Canadian myself - but hopefully one day we can expand things more meaningfully to the rest of the world.
