Heya, feedback for Lesson 4. Been a while since I last did any community critiques, but I hope this will be useful.

Organic forms with contour curve.

Good work. Your linework looks confident and made with a single stroke. Some of the sausages look like they were made with multiple strokes, but they're cleanly done, so that's fine. Regarding the middle line that goes through the middle of the sausage, they're well drawn but a lot of them don't go through the whole sausage, they seem to stop just before the end. I advise drawing that middle line all the way through the whole sausage since this line forms the minor axis for the contour curves.

As for the contour curves, they're well drawn, and most of them hook over at the ends quite nicely, however, but not all of them have that hook. Also, it appears that some contour curves don't align so well with the minor axis formed by the midline. Any ellipses you draw inside sausages have to be aligned to the sausage's midline, and contour curves are based on ellipses. Definitely take care to align all contours and ellipses to the minor axis, especially in L5 (where you will draw more sausages and contours for animals).

On the whole, I think you got the right idea for sausages and the contours.

Insect drawings.

L4 is the first lesson where we have to put forms on top of each other to construct insects that exist in believable 3D space -- and I think you have succeeded here. I can see you're making a lot of effort to use sausages, ellipses/spheres, and boxes to construct all your insects, and piling these forms on top of each other. And the places where you put additional forms on top of those basic forms, they are also following the contours of the basic forms. (Eg. The back plates of the scorpion, wings of the praying mantis.) Well done with this!

Several areas I think you can work on:

• Some insect heads (plus scorpion body) have boxes drawn around them. It appears that you used those boxes to help you orient the shape/perspective of the head before you drew the actual head, usually a separate ellipse/form. Uncomfy advises not to do that because that's considered "subtractive construction" (see here for more info). He also says (on official critiques) that every line we make has to contribute to the final construction of the animal. Moving forward, try to use those forms/boxes as a starting point to put additional forms on top of them (ie. "additive construction"), instead of using them like an external guidance and drawing new forms inside them.

• It's a bit hard to see this since the drawings are a bit small, but when you connect multiple sausages together for the insect legs, put a contour curve where the sausage ends overlap, to show where the leg joint is. (Uncomfy's example here.)

• Your overall insect constructions are solid and simple, which is a good foundation. I think your insects could have more wrapping forms added to them - like in Uncomfy's example here. I encourage you to experiment with adding more forms to this foundation, wrapping them or piling them on top of what you already drew. You'll be doing more of this in L5.

• This is nitpicky, but the hairs/spikes on the tarantula's body look like 2D lines because they aren't completely closed (like all the other forms). I suggest closing them completely (see above linked example).

• Your first wasp drawing is a bit small but the other drawings are bigger, which is good. But it looks like you're using a thicker fineliner for these drawings? The lineweight is quite thick. If you don't have a thinner fineliner, I suggest drawing the insects bigger so they fill the whole A4 paper. That way you can add more detail like additional forms and textures and they will stay visible even if the lineweight is thick. (It's a bit hard to tell what size fineliner you're using, so if you are using 0.5mm, sorry for the mistake).

Overall -

I think you did a good job with the insects, you're drawing all the construction properly and the 3D quality is emerging in your drawings, and it looks like you understand the principles of construction in this lesson. Take care with the little details, and in L5 definitely practice how to add more forms to your structures in order to build up more detail and 3D quality. Keep up the good work!
