Hi there!

Going right into the critique, your superimposed lines are looking great. Clean, smooth, fraying only on the tail end. Great job. Regarding your ghosted lines, there is a minimal amount of wobbling, same goes for ghosted planes, but overall I'd say well done.

Moving on to ellipses, they're looking pretty decent. Some of them are a little wobbly and bumpy, but other than that the execution is looking good. You've drawn though them well, they do leave their borders at times, but that's usually going to be the case when you're getting used to them. Just keep that in mind. Only thing I'd note is I would have liked to see some ellipses with narrower degrees, as the majority of yours are either circles or rather wide. But, all in all, good job here too! Funnels are looking good too, same slight wobbles as previously mentioned, and there are only a few ellipses that fall out of alignment.

Regarding rough perspective, your line quality goes down a bit, which is expected as this exercise is super difficult, but I will note that there is no need to go over your lines twice. If you were trying to add line weight, it should be very subtle, and you can read more on that here. Other than that, good work.

Rotated boxes look fairly good, they are nicely cuboid, the majority rotate well -- aside from those pesky corner boxes. The only thing I can point out really is the bottom left quadrant, where you have a long boy box on the outer edge -- this is because your center box in that particular quadrant is distorted, so the long box follows an incorrect line. But, this exercise was meant to be hard -- harder than your current level at that, and all in all you did good.

Great job with the organic perspective too! I will once again remind you of line weight, which I linked earlier in this review, as something you may want to read up a bit on. Scale is looking good, boxes rotate around nicely. Well done!

All in all, great submission, great job! :) Looking forward to the 250 boxes. Good luck!
