Hello

Thank you for doing your revision again. This is another step in the right direction. The direction of your light source is very clear in the way you're drawing your shadow shapes. As the viewer I would know that the light is coming from the top left, even without the arrow to show me, good job.

But you are still not clearly telling the viewer which form is on top and which one is underneath. If I knock back some of your work to make the forms look more opaque we can see what order they are stacked here https://imgur.com/Xu0QypO I know from the numbering system that you drew number 4 last, so it is resting on top of the others, partially covering them up. (and 3 partially covers 1 and 2, and 2 partially covers 1) Here's a really gross example of some sweets that follow similar behaviour to organic intersections, in case a real world example will help you visualize what we're aiming for: https://imgur.com/a/ByGvV3G

But of course, in this exercise we draw through our forms, so your homework should look something like this https://imgur.com/vzyGDwp where the forms are drawn in their entirety but the shadows are not there are no shadows drawn inside the silhouette of number 4 (the top most form) please carefully study those two edits and compare them to the page you posted. Can you see which shadows were removed and most importantly why? If not, please let me know and I will try to explain it another way. If you feel confident that you understand that we do not draw through our shadows, they get cut off when they pass behind another object, then I want you to complete one more page and clearly demonstrate this principle, numbering your forms in the order that you draw them once again.

On the other two points: With the degree of contour curves I can assure you that this image is correct. https://imgur.com/a/yDBbayD in fact, it is the same idea as the draw-over and notes I gave you on your organic forms exercise here: https://imgur.com/IdTTJjH "Ellipses are narrower at the near end and wider at the far end" If you are unable to read my handwitten notes, could you please let me know? I'm happy to type them out for you, but giving you feedback that you can't read is just a waste of time.

The wide-narrow-wide pattern you describe is what we see when we're looking at the side of a cylindrical object, or sausage form, as seen in this photo I took of a roll of paper with bands round it https://imgur.com/a/qHTLXtw

And here is how the contour lines appear when we look at the left end of the object https://imgur.com/a/GuPpiU0 I hope it is quite clear that the degree of the contour curves get wider as the object gets further away.

Finally on your texture practice "I'm trying to collect my visual library of texture. I download the reference photos in pin message of lesson 2 and draw them bit by bit. But my problem is that I don't know that I do it right or wrong. Do you have any suggestion for that?" If you want to keep studying textures, that's great, we have the optional texture challenge info here https://drawabox.com/lesson/25textures

If you're not sure if you're doing it right, that's understandable, and you should seek feedback on your work. I hope you can understand that I have already given you a rather substantial ammount of feedback, and marked your texture work as complete. I'm trying to prioritize the feedback and information I give you to be what you need to set you up to succeed in lesson 3 (textures are optional in lesson 3). So please forgive me for asking you to share your new texture work on the discord (either in the lesson 2 channel or advanced challenges) for additional feedback, if you want it. If you have a question about the feedback I've already given you on your textures, or the instructions given for the exercise, I'll do my best to answer.
