Hello! Crits come in quite slowly these days, so I hope you don't mind. Here's my crit!

Before I start, I think its worth mentioning to try to take photos of individual pages at a time. This makes the critting process a little easier. In addition, try to ensure that the pages are in order. This, again, makes the process of critting a little easier.

On your lines, I'd say they're okay. There is definitely evidence that you've ghosted them a decent amount, and executed with relative confidence. This is good. However, there is arcing and curving in your lines. This hints to me that you're mixing some pivots. In addition, especially in your ghosted lines, you're overshooting quite a bit. This tells me that your ghosting may be a little distracted. While accuracy is not a priority in DaB, its still of some importance. So do try to keep that in mind.

Ellipse wise, I think they need a little bit of work. As with your lines, I find your ghosting here a little distracted. As a result, your ellipses aren't exactly true to the ghosting. This also results in some mishapen ellipses, especially in the funnels exercise. On that note, your ellipses aren't really aligned to the minor axis well. Try to adjust for that. And, you should try to draw through your ellipses twice, thrice maximum. Don't go overboard in this regard.

For your boxes, I'd once again say they're okay. Rough perspective is fine. For the rotated boxes, you need to ensure that all faces, including the bottom ones, should converge at different points. This gives a proper idea of rotation as the vps move around the page. I recommend giving this guide a read: https://www.reddit.com/r/ArtFundamentals/comments/cqvxap/i_created_an_extra_rotated_boxes_guide_for_people/. Not a bad attempt, though. For your organic perspective, you need to draw more boxes. This will give the better illusion of depth. In addition, don't repeat your lines, even if they're incorrect. This only draws more attention to them. And, you're missing a page of the plotted perspective.

While I think this is a decent attempt, and that you're more or less good to go for the next lesson, I want you to finish up your work first, meaning...
