Ah, thank you so much for your feedback - I appreciate it very much! Truth be told, I'm so delighted to read so many useful tips - I'll study carefully my mistakes and try to correct them, doing warm-ups!

About missing pages - it seems I simply didn't take a photo of them for some mysterious reason. I updated it, so it should be fine now. Well, in the case of rough perspective - the second page has incorrect correction lines as well. I somehow missed it - I guess, I'll try this exercise once again.

Well, to be honest, the second one, more "round", page is my second attempt at the rotated boxes. ^^" I guess I didn't do very well. I've done this exercise twice by mistake - it was very challenging, though.

Anyway, thank you once again for your effort in reviewing my homework. Much appreciated! :D

Also, I really want to rate your critique as very helpful, but I'm a total noob and I'm not sure - if I'll change the button to orange, it means I agree, right? I'm not sure, lol, and I don't want to "criticize your critique" by mistake! Hahaha.
