Hey, TA qzhans here!

First, superimposed lines. You’ve kept fraying to a minimum here and there’s some good confidence throughout. Nice work.

Moving onto ghosted lines, that confidence continues. I also like that you tried a variety of different lengths and angles.

Your ghosted planes are some of the same nice stuff. I do notice you drew an extra line here and there, perhaps to correct some perceived mistake. Remember that all lines we put down are law, and laying down more lines to fix something will only create more contradictions and draw eyes to a mistake.

Moving onto your ellipse tables, I like that you're keeping your ellipses tightly packed within the bounds that you've set. There's expected room for improvement in getting your ellipses to be tight and tidy, but drawing through with confidence is more important at this stage, which you are.

Your ellipses in planes, the tidiness improves a bit. You also don’t stretch out your ellipses needlessly to hit the bounds, opting instead for a confident ellipse.

Next, your funnels generally do a good job of aligning to the minor axis that you've set and I have no complaints.

No problems with plotted perspective either!

For your rough perspective, I’m pleased to see that you are applying the error checking method correctly, extending your lines parallelly back to the horizon line instead of directly to the vanishing point. I do see a few issues with keeping the verticals perpendicular to the horizon line and the horizontals parallel to it, so watch out for that. Also, the problem of re-drawing lines pops up in a few places here; continue to remember that confidence is more important than accuracy for these exercises.

And now, the one you’ve been waiting for: rotated boxes. Before anything, I wanted to congratulate you on its completion; it's not something you're really supposed to be ready for. In general, I like how you’ve structured this exercise, keeping the gaps between boxes consistent and drawing through each box. As a result, the rotation is fairly convincing. The only thing I could nitpick on is that there are a few double lines here and there, but I much prefer the confident way you did it rather than a wobbly reinforce.

Finally, onto organic perspective. In general, your boxes do a good job of shrinking and growing as they move through space. I'm pleased to see a little bit of overlapping here and there as well (although I do think you could've done a bit more). There's work to be done in getting those parallel lines to converge to their shared vanishing point, but you can iron that out with the box challenge. The problem I do want to address here is how sketchy you became; it looks to me like an attempt to create depth with line weight that got out of hand. Honestly, I can’t really fault you for it because you executed the lines with confidence, but I’d like you to continue to keep in mind going forward that this kind of thing does take away from the clean look we’re going for.

Overall, a strong submission. I’m excited to see you take these fundamentals into the rest of Drawabox!
