Thinking in 3D

your organic arrows i feel are your weakest submissions but it's hard to say why exactly. there are some good overlapping arrows in there but there are also plenty that don't feel they recede into space but just go from side to side like they lay on a table. i guess i would say to overlap and exaggerate scale change even more. it will feel uncomfortable to draw. Also try to gradate your shading more like his example shows-- tighter where the form first turns and less as it gets further from the turn.

your org forms with contours look really good. there are a few ellipses that still dont quite reach your outer edges but it will get better with more practice. sometimes your degrees are still too similar within one sausage form. i feel your sausages get a bit long which is not bad for the texture dissection exercise but i would focus on Uncomfortables instructions about keeping 2 spheres on the edges of a tube idea. the ones with just the contours instead of ellipses has better sausage forms though that are not as long.

Texture and Detail

i think you have excellent observation skills and skills of drawing what you see. i think your coral study in the middle row is excellent and professional. all 3 texture analyses are really excellent. your dissections are really successful as well and you disperse the density of the textures really well. Raspberry and dragon fruit didnt show much of a highlight/dispersement but corn texture looks so good, i also tried to do corn and yours is lot more successful than mine. you did the avocado multiple times for the center dissection which is kinda cheating but I accept it. this one took forever because just finding the references takes so long. i appreciate that you did this over more than 2 years. i did this lesson over 1 year and felt i am so slow.

Construction

i think the one with so many forms is so ambitious and great! i think you have a great sense of form, shallow perspective, and good line quality. i like that you chose to draw through the form intersection as well which i was surprised was not in the instructions for this assignment as it seems so necessary to really understand form but it is challenging. your forms are drawn well but some of your intersections do confuse me for example in img_0008, in the lower left corner it is not clear to me how that top plane intersects the box on top of it. and just to the right of that is a box with its lower left corner showing a dissection that should really be obscured by the form in front of it. maybe that's the page you did a long time ago though. in img_10 the lower left sphere and cone intersect but i feel the intersection line should bend the other way following the contours of the sphere, but it's hard to tell because you didnt shade it. Same with the pyramid above that. the pramid on the lower right corner is really hard to understand in img10 too because there is no shading or line weight to help make it clear and as a result the intersection on it doesnt make sense to me. the cone above that pyramid on the right side of img10 is trying to intersect a sphere and cylinder but it isnt complete or successful and needed more time. i think your box forms on this page look excellent but the page would have benefited from shading. img11 as well i can see there are 2 intersection lines on the sphere towards the center that should be convex instead of concave i think so the intersection follows the contours of the sphere. the pyramid in the right corner intersects the cylinder in a way that doesnt make sense to me. it seems like 2 flat side faces of the pyramid intersect the rounded side face of the cylinder and that is all we should see because the back right face of the cylinder is turned away from us, however you have an intersection line on the far right face of the pyramid where it intersects nothing. the point of this exercise was to make forms that look like they have similar levels of perspective and with good line quality and i think you achieved this very well.
