Third time I'm critiquing somebody, alrighty

Lines

Superimposed Lines seems confident enough. Though I do see that your lines arc a bit. This might be due to sitting/drawing position.

Ghosted Lines looks alright. Ghosting lines means to plan out your lines, and to know roughly what specific motion your shoulder needs to make to make the mark you're working on. It looks as though you're doing the execution step correctly (making the stroke, with confidence), but you might have not prepared enough for the line you're going to draw. If anything, you shouldn't rush the preparation phase of ghosting. Preparation lets your arm know what it's supposed to do.

Ghosted Planes looks really good. From the looks of it, you did more preparation, resulting in straighter lines. Nice job. You might want to work on less undershooting/overshooting. Practice on the timing of lifting your pen as it moves past the end point.

Ellipses

The Tables of Ellipses look rough. But this is the first time you're ghosting something other than a line, so don't be hard on yourself. I'd say you should ghost/prepare more, and when you're executing the mark, relax. Don't think too much on how it's going to turn out. Just let your arm do its thing, and press onward.

You might be worrying too much on accuracy. Do keep in mind that you should prioritize confidence over everything else. If your ellipse overshoots but it's smooth, that's pretty good. I can see you got better with it, so just let focus on confidence more.

The Ellipses in Planes looks decent. There are some cases where you let your arm do its thing, and there are some where you tried controlling where your pen goes. Again, confidence is a needful choice for smooth strokes.

Funnels look pretty good. Though some look like you hesitated, it looks like you got more confident. Nice job.

Boxes

Plotted Perspective is done right.

Rough Perspective looks rough. I'm seeing a lot more curving in your lines. If that is due to hesitation, it's understandable, as you're worrying about more than just lines in this exercise. If anything, do not forget the ghosting method and its purpose. It's meant to prepare you for the best mark possible. Also, don't be afraid of overlapping lines/boxes.

Rotated Boxes looks iffy. Nice job on straighter lines. Your gaps weren't narrow enough to use neighboring lines to guess off of. You might want to spend more time planning. Really put more thought onto the points of your lines.

Organic Perspective looks pretty good. Though you shouldn't be putting extra lines for just one mark. Your lines got straighter though, nice work at your first time on this spatial problem.

Conclusion

Really work on confidence. When you're ready to make a mark, really make sure you're ready to trust your arm to do its best. You should be able to commit to the motion you're going to make. Any and all opportunity to make a mistake passes by as you make the mark, so just keep pushing onward with confidence. This may need more preparation in the ghosting. If you're rushing it, don't. It's better to make a few confident strokes than many wobbly lines.

Drawing confidently is a choice. You might want to take a piece of paper and just draw random lines. This will tell you that you can pull off smooth strokes if you just let your arm do it.

I'm also seeing some comments you made on your own work. Again, do not be hard on yourself. This is our first time playing with these concepts, so we should only strive for doing things the best of our current ability. If you fail horribly, that's okay. Some of these exercises are meant for us to flop the first time.
