thank you so much for such a comprehensive and positive critique! I'm feeling proud of myself, especially after reading the rotated boxes one. I actually did some more practice before doing that exercise, basically doing a rough perspective exercise of 2 vanishing points and 3 vanishing point, just to get the "rules" clear (2 sets of straight lines for 1 point perspective, 1 set for 2 point, and none for 3).

about the extra lines in rough perspective, those were an attempt to make one surface clear, like in the plotted perspective exercise, because I was feeling a little woozy and couldn't quickly figure out which surface was toward me (you know that thing that happens when you're looking at a box with the all the lines drawn from some angles it looks inside-out?). that's it.

Thank you again for this amazing critique. I'm feeling a lot more confident and I'm gonna start with the challenge tomorrow!
