Hey there! You are absolutely correct in that these exercises are very testing on your patience. You should absolutely feel very proud that you've completed them, and even more so that you've gone back and critiqued yourself.

With that said, I would like to offer you my input as well. :)

Superimposed lines look good. Fraying is only on one end, I can see you were focused and took the time to reposition your pen after each stroke. Well done! Your ghosted lines look good too, no wobbling, confidently executed line. The only thing I can see is maybe a bit of arcing. Overall, nice work here too, and great work with your ghosted planes too.

Excellent work with the ellipses as well. There are places where you could have maybe fit another one or two smaller ellipses in to the gaps, but this would be an additional optional. You understand the purpose of the exercise well and it is well done. The same goes for the ellipses in planes. Your funnels look great. Your focus and frustration truly paid off! A very minor thing, which I am certain you understand but, as you've said, your hand didn't listen -- I'd like to point you to this section. You didn't do anything wrong, and as I've said you clearly understand it very well, but I figured it's better to reiterate the information.

The boxes definitely take a lot of time. This is where your patience really gets tested. Try to keep calm while you're doing them. There is no need to get anxious to finish the boxes, take each one separately and try to enjoy the process of drawing out every single box. Much easier said than done, I know. That said, rough perspective is looking good! I can definitely see where you impulsively went over your lines, but you recognize the issue so that's ok.

Great work with the rotated boxes exercise! That really is a tough one. You've done well in keeping the faces of your boxes aligned to each other, and the boxes themselves are a cuboid shape, so great job. :)

The only remark regarding organic perspective would be that the scale isn't quite as dramatic. I'd like to have seen the largest boxes be a little bit larger, and the smallest be a bit smaller. Also, it might be worth revisiting this bit of text here, since you did mention your struggle with rotation. Rotation is very difficult, and this is still a good execution of the homework, and I can see big improvement towards the last frame. Overall, this is an excellent submission and I'm looking forward to your 250 boxes!
