Okay, I'm not going to say start over, but I would like to see you revisit a lot of these exercises.

Lines

Your superimposed lines need work. Since you've got fraying only at one end, you're starting out fine, but a lot of these tend to miss the mark by huge margin. They don't need to be perfect, but it feels like you're rushing it. You need to try long lines, short lines. Mix it up.

Ghosted lines got there in the end, but there's a lot of wobbling. Remember to quickly execute your line after ghosting several times. Try to be careful, you're overshooting your lines quite a bit. You need to get in the mindset that the points you're putting down aren't just suggestions. Ghost your line from one point to the other, then execute. You can draw at a different angle if you think it might help.

Ghosted planes aren't too bad, but try not to repeat lines. Also, slow down. Again it seems like you're rushing through it. Ghost your lines more, as they seem to miss the mark often. Be careful with curving on your lines too. If you have a tendency to curve lines one way, you can try to correct it through consistent practice and consciously curving it the other way slightly.

Ellipses

Tables of ellipses is messy. We're not aiming for something super clean, but I just think you were rushing again. Slow down, this isn't a race. You're doing more harm to yourself in the long run. Ghost your ellipses. Draw through them 2-3 times. Really think about what you're putting down, and then execute your ellipses quickly and confidently.

Ellipses in planes have a lot of wobble. You need to be more confident. There are a couple in there that I think were done well, though.

Funnels, I think you were getting better with your ellipses by this point. They're still a bit all over the place, but overall, I think better than before.

Boxes

Plotted perspective is good. Not really ever much to say about it.

Rough perspective, I think you're guessing too much with some of your boxes. At least on your first page, I think you just weren't putting down points to ghost to, and your lines and boxes suffered greatly. Again, I think you were rushing through this. As for the second page, it looks like you've gone and ruled out your initial square for each box which you shouldn't be doing. The only time you should be using a ruler is when drawing your horizon line.

So stop guessing, plot out the points for each box, and don't use a ruler.

Rotated boxes is a pretty hard exercise. Looking into it, I can see the boxes do indeed rotate in space. Your line quality is pretty messy, so you need to watch for that, but overall it's not too bad, if hard to see. I think where you've put the hatching on inside faces helped with this. Just be careful, don't repeat lines.

Organic perspective isn't too bad, I think you got the gist of it. A lot of the convergence and divergences in your boxes can be corrected through the 250 Box Challenge. It's not easy to get thrown right into drawing these objects in 3d space, but I think you'll see a lot of improvement.

Overall, I'd like to see a few more exercises before saying this is complete. You need to work on your lines and ellipses at least. I'll put the details below.

Just remember to try not rush everything, ghost every single line you do, and then execute that quickly and confidently.
