Hi~ Let’s look through it, then~

The line section looks good! I’d recommend making the start/end points of your ghosted lines/planes smaller, since, the idea is that a line should, if perfect, swallow them both, but it looks like you figured this out by yourself, since that aspect of them improves considerably throughout the set, and even more throughout the submission- nice job there.

The ellipses look good, too. Careful to only go around them 2-3 times, though, ideally 2. Also, they’ll occasionally stiffen up in the ellipses in planes exercise, so be mindful of that. It’s more important for them to be rounded, than it is for them to be accurate, so don’t stress!

Finally, nice job on the box section. It looks like you might’ve used a ruler for the front faces of the rough perspective exercise. This is incorrect, but not a huge problem. Be careful not to correct incorrect lines, though. If they’re wrong, they’re wrong. Despite being super difficult exercises, both the rotated boxes exercise and the organic perspective exercise are well done. In the latter, though, be careful with your weight. It should be applied locally (meaning, to the part of the line that’s overlapping something, not the entirety of the line), and subtly (meaning, only once.) Careful not to apply it to the inner lines, too- that makes the box look less like a box, and more like a collection of lines.

Despite all this, this is a solid submission, so fantastic work, and good luck on the challenge!
