Alright, here's what I think:

Lines

For some of your super imposed lines, I noticed fraying on both ends. To elaborate, the super imposed lines drawn straight horizontally. Although it isn't present in your other super imposed lines, a reminder to position your pen at the beginning of each line/dot (depending on what you're doing.)

While there is a slight wobble in your ghosted lines, I can see how you're going for bold lines. They're drawn cleanly and boldly, so nice job!

I'm not exactly sure if you did your ghosted planes, then added the ellipses, but I request that you do these. You don't have to post them, I just recommend it as it's part of the assignments.

Ellipses

Although there are some overlaps in your ellipse tables, they're really well done. So I congratulate you for that. Same for the ellipses in planes, while they sometimes go out of bounds, they are smooth and confident.

Your funnels were also generally aligned to the minor axis, therefore, you did really good job with your ellipses. :>

Boxes

While you did a nice job with your plotted perspective, it is noted that you have to draw through the boxes. I'd request something simillar for your ghosted planes: draw through those boxes, but you don't have to post it.

Nice job on your rotated boxes and rough perspective. Your rotated boxes are nice and clean, as well as neatly packed and a clear indication of rotating.

Your organic perspective was done really well, I like how the flow or gesture of the lines fit how the boxes are freely rotated in space. Although you shouldn't strive for visually-pleasing exercises, your organic perspective was really nice.

Conclusion

The assignments you submitted were done really well and met the assignment requirements. I'll ask you to finish the ghosted planes, and draw through the boxes on your plotted perspective. Otherwise, I'll mark the lesson as complete.
