Hi! I took a look at your work, so I'll be sharing some thoughts if you don't mind.

I have to say that everything feels pretty solid and well executed to me. Especially in the "lines" and "ellipses" sections, your strokes are confident, without wobbling, and you also have a nice degree of accuracy. It feels like you understood the exercises and their purposes, so I've nothing much to say here.

I see some repeating strokes on the "plotted perspective" exercises, and I know you should try and avoid that, but otherwise also this exercise seems executed according to the request.

For the rotated box exercise, it feels like you understood the principles and applied it in a pretty extreme way! The boxes at the extreme corners are missing, maybe because the rotation is so steep that we wouldn't be able to see that box anyway, if not behind all of the other boxes? Anyway, I'd say you got the point. The gaps between the boxes are pretty consistent and the strokes are confident too.

On the organic perspective, some of them are difficult to read but otherwise also here I think you've applied the exercise instructions correctly.

Overall I think you've done a nice job, keep up the good work!

I've nothing more to add, I hope I've been helpful.

Side note: I see that you linked your work via WeTransfer: keep in mind that the link will expire in a few days and after that date people will not be able to see it anymore. I hope you get more reviews before that date, but if not, remember to update the link until necessary.
