Superimposed lines:

I see you've tried a variety of lines (lots of curvy ones too!) and I think they're good for the most part. A bit of fraying here and there, but I think we all started that way and it gets better the farther you go in the lessons!

Ghosted Lines:

Good points, the line confidence could use a bit of work. Don't worry if you miss it, draw in one confident smooth stroke. The wobble indicates slow, meticulous drawing, whereas we're aiming for confidence here. Some of the longer lines arc a little bit so remember to draw from the shoulder to the best of your current ability (I struggle with feeling like I have no control when I'm drawing from the shoulder, but it gets better with time!)

Planes:

Nice use of space! Again, try for as even and as smooth of a line as possible. There's some wobble and a few of the diagonal lines arc (I know it's hard to keep perfectly straight especially with long ones!) and end up crossing off-center. If you're nervous about missing the dots or worry that you'll over/undershoot you could open a random page and do some shoulder-led lines to work up confidence (helped me a lot with the box challenge).

Ellipses:

Nice! You've drwan through well and the circular/round/curved shapes seem to suit you - these look a lot more confident! Overall good job making them snug!

Ellipses in planes:

They are very precisely touching all sides - good job on that! Just make sure you're not slowing down to achieve that and making the ellipse wonky, it's okay to do more than two passes and get a bit closer or looser with them. All I can nitpick is a slightly smoother pass/bit more confidence in your strokes.

Funnels

They look awesome! Good job, I can see that you got the right idea and the small spaces where they aren't snug are no big deal.

Plotted perspective

Looks very neat, nice cross-hatching, well done!

Rough perspective

Lines a bit unstable, but you did well. The bottom third of each paper has boxes with curving vertical lines, so remember to ghost from point to point, as many times as you need to, to feel confident in executing a straight (as straight as you can) line from one point to another. These look like you might've gone slowly to make sure you hit the point, rather than confidently, not worrying even if you overshoot.

Rotated boxes

The left side (looking at the paper) looks great in the upper corner, a bit more unstable down. Try to get the lines as straight and parallel to the guiding lines around them. All in all, good job, this is a very hard one.

Organic perspective

On the first page, the top third has a few boxes at the far end that are as big as the boxes in the middle when they should be getting smaller gradually. Also the boxes at the front are almost the same size. I think you nailed it around the middle, just try to keep that gradual. The second third starts great but has a same-y middle and I think you nailed in on the third, great job! I can see you fixed it up on the second page, so I'm sure you saw it yourself, but I thougth it'd mention it just in case.

All in all, I think you're doing well! A bit more confidence and making sure to draw from the shoulder and you're set :D
