Hello, I hope you find my feedback useful.

I think your lines are pretty solid, it seems that you understand how to create confident lines well, there's no wobbling and it looks like they are planned out.

Your ellipses are also good, you draw through them twice, they don't overlap with other ellipses, or go out of bounds.

Your boxes are okay, but I think they can be a bit better. Something that'll hep make your boxes look more solid would be to add lineweight to the outer lines of them. Another problem I notice is that the rotated boxes aren't actually rotating, they are mostly following a single vanishing point and slowly converging to it. When rotating the boxes that are further out from the center. The vanishing point should change to show the rotation of the box https://d15v304a6xpq4b.cloudfront.net/lesson_images/d73eea49.jpg.

Overall, I think you understand the lesson pretty well. I don't think it would be very useful to redo the rotating boxes exercise since you'll be doing the 250 box challenge next and you'll gain plenty of experience with a variety of vanishing points and perspectives.
