Hey Oroi! You've waited a while, huh.

Your line exercises look good. The curved superimposed ones look a bit fuzzy, but that'll improve with enough time and practice.

Ellipse exercises are also good. Some of the ellipses in the Funnels don't have their minor axis aligned to the middle line, just remember next time to draw them so that they're cleanly cut in half by the middle line.

Your box exercises are well done! You got a good grasp of one-point perspective by the end of Rough Perspective. Some of the Organic Perspective boxes are definitely not cubes, but the important part is that they look and feel solid.
