Your superimposed lines, in my opinion, are pretty good. You don't fray in both ends, and that's nice.

I think your ghosted lines are ok, too.

I noticed that in your ghosted planes you didn't draw the x that goes from corner to corner first; instead, the other. That result in a misaligned middle point. Remember that you draw the "X" that goes from the corner first to determine the center of a 3d plane.

I would recommend to ghost more your ellipses -draw them with enough confidence-. Talking about ellipses, you should always remark them two times (or three, maximum). I saw that in some ellipses in the funnels exercise you didn't do that. You shall do it always.

Your plotted perspective looks fine

Recall to ghost more in your rough perspective.

I think your rotated boxes are good, too

And in your organic perspective -although the boxes aren't completely ok - I'll say that don't worry. You'll become better with the 250 box challenge!

I hope this was useful, and it's just my opinion. Sorry for bad english, too. Good luck!
