great job with dissection i like your economic use of strokes and the texture shadows well done

nice job with texture analysis it really have 3d form

the crumble paper sorry if u misunderstand i mean to make the three part one copy and notes and other construction texture from what u opserved (copy) one so i need to see one from dense to sparse and notes

nice job with organic forms

form intersection drawn well with confidance but need minor axis for cone

i see u over shad the intersected part some look like mess but next time try to see pinned post of this and draw them in same size and full page like demo hw u need more grasp of this

Organic Arrows

Starting by the organic arrows they are drawn with a good deal of confidence, which helps to capture the fluidity with which they move through space

your making some good attempts at the perspective of the ribbon but push more. The main issue here though is that you are not aware that the negative space between the zigzagging sections of the ribbon should decrease as it moves further away, as shown here ( https://d15v304a6xpq4b.cloudfront.net/lesson_images/011d064f.jpg ), this is the only thing missing for your arrows to look tridimensional. this is the only thing missing for your arrows to look tridimensional.

you are on the right track keep pushing

there is one thing i want to adress back then to organic intersection i forgot to see another page in revsion so please back to the notes and read it and find the mistakes and try to think of it clearly
