So, I'll be grading your homework today.

Superimposed Lines: I see a lot of fraying on both sides here on the first page, but your second is better. The curving lines on both look great. Your lines aren’t wobbly either. Overall, you did a good job here.

Ghosted Lines: No arcing or wobbling to be found here. Again, good job.

Ellipses in Planes: You have some lines that wobble a bit, but they’re fine for the most part. Your ellipses don't quite touch all sides, but that's an accuracy thing that'll resolve with practice.

Tables of Ellipses: These all look good too. Drawn through twice like Uncomfortable asked, fitting snugly in the box for the most part, and none are wobbly. Some are drawn through a bit more than they need to be though. Two or three times is all we need. Otherwise, it starts to look messy. Still, good.

Funnels: Your ellipses align with the minor axis for the most part. In a few places, they overlap one another, but that’s because you draw through a lot. Besides that, they touch like they’re supposed to pretty consistently. These are also good.

Plotted Perspective: These look great. I see nothing wrong here.

Rough Perspective: Also looks really great. Your width lines are parallel with the horizon for the most part and your height lines are perpendicular with it as well. And your other lines go right back where they're supposed to. No guesswork going on here.

Rotated Boxes: This one here is amazing! Your boxes are drawn through, rotating incredibly well, and you kept them close together. You absolutely knocked it out of the park with this one, especially with how difficult this exercise is.

Organic Perspective: It looks like you got your line weight backwards a bit for some of these, but that’s alright. Your boxes don’t look bad and they shrink with distance. So these are good too.

I’d say you’re ready for the 250 box challenge
