Nice work overall. I think you demonstrated a good deal of growth and improvement over the first 200 or so, where you gradually shifted your focus more to how your lines would converge in sets of 4 (instead of having lines converge in pairs, or three together with one flying off). It seemed throughout these first couple hundred you were very well focused on your vanishing points, and keeping them grouped in fours.

Your last 50 however definitely seemed to get a bit lazy - maybe you got burnt out and tired from the exercise, perhaps you were trying to get it all done too quickly and move on, and maybe you weren't doing as much drawing outside of Drawabox (the whole drawing for fun thing) to be able to dedicate your full focus with each line when doing this exercise. Whatever the cause, I think in these last 50 you're slipping back into patterns of having lines converge in pairs (where you're thinking too much about the lines that share a plane, rather than trying to keep all four converging together). Also, your very last box seems to eliminate vanishing points altogether, trying to keep all three sets of four lines actually parallel on the page (in 2D space). Even when our vanishing points are super far away, we still need to be aware of the fact that they are going to be converging, if slowly.

Overall you did well, so I think it's worth overlooking that last 50 and judging you based on the first 200.

Just so you know, you will probably need to submit lesson 1 and get it approved on here in order to submit lesson 2 (I'm not totally sure how the prerequisite submission thing works) but if you let me know then I'll submit a filler comment to get the approvals needed for a badge!
