Hey, Doc! Perhaps you recognize me, but anyhow, I'm Keisari and I'll be the one responsible for critiquing your Lesson 2 submission today. Before we proceed, congratulations on going through Lesson 2!

Thinking in 3D

Your Organic Arrows look good. You're drawing confidently, making correct use of line weight and hatching, and making good use of space. Some of them are sloppy, but that'll improve with practice. One thing I'd like to suggest, though, is that you push their foreshortening further and be more adventurous exploring 3D space -- try and make them approach or get distanced from the viewer at more extreme rates; let arrow segments overlap other segments of the same arrow; vary the spacing between and size of each fold more... Experiment and exaggerate. That will further your understanding of 3D space.

Your Organic Forms also look great and I don't have much to say about them, although it seems you should work on the confidence of your ellipses.

Texture and Detail

Overall, your textures are fantastic and I struggled to find anything to critique. Something I noticed in your Texture Analysis exercise is that the black bars are pretty clearly visible, so you should try and push the shadows more in order to achieve a more seamless transition. On your Dissections, I noticed you seem to do form shading on a couple textures, such as this one and this one. As tempting as it might be, you should not fill in anything but cast shadows, be it form shading, color variation or anything else, even if it's difficult to convey a texture that way. Generally, if you can't properly convey a texture with only cast shadows, you should probably stay away from it in Drawabox's approach.

Construction

For your Form Intersections exercise, you did well abiding to the main goal of doing consistent and shallow foreshortening, albeit there are some cases where you did more extreme foreshortening, mainly in your box-only page, but I presume that to be unintentional. Your forms are very well constructed, you're applying hatching correctly and although it's secondary, you also did great on your intersections. Even then, if you wish to understand them further, I'd recommend checking out the Forms Intersection First Aid Pack and this website, if you haven't already.

Your Organic Intersections also look pretty good -- they're simple, drawn through, confident and you did very well regarding their contour lines and making them stable, capturing their water baloon properties, although I suggest you push their physics a bit further in that regard -- for example, this sausage should sag into the crevices inbetween the sausages below it, although I understand it can be difficult to get that right markmaking-wise.
