Thanks for the feedback.

I had particularly missed how my verticals where slanted in 2 and 1 point perspective. I understood the concept, that they should be perpendicular, but my lines weren't matching this knowledge. I'll also double-down my focus on confidence over accuracy.

I want to say that my biggest breakthrough so far was in the rotated boxes homework, where I went from "I have no idea how I'm supposed to add all these boxes," to "I see the lines," within the days it took me to finish it. I just kept the drawing on the desk, and would "understand" where some of the lines should go. It's not perfect and I'm still somewhat shaky with the further diagonal boxes, but this was a clear a sign to me that a lot of the learning is happening on a subconscious level. By the end I even found it fun to sit down and figure out how to add the next boxes. Whenever I look at it, I'm surprised that I managed to make it.

Thanks again for the feedback, I'll get on the 250 Boxes Challenge.
