Your lines don't look too bad. They get a little wobbly in the perspective section, but I'm guessing that's because your brain is on overload trying to work out where everything should be going. Don't forget that those boxes are made up of lines, so you should treat them just like the lines you drew for the ghosted lines and planes exercises.

Some of your ellipses in planes are not touching all 4 sides of the plane. I don't think you need to redo them, but when you repeat them for warmups you may need to ghost them a bit more before you put the ink down. It's going to be important for you to do them properly when you get to drawing cylinders. Additionally, the minor axes of your ellipses in the funnel of ellipses exercise should be aligned with the center line. Again, you don't need to redo them because you did a pretty good job most of the time. Just keep that in mind for when you repeat the exercise during warmups.

The second box down in the second panel of your first page of the organic perspecitive exercise, the mor vertical lines diverge significantly. This should never happen. Those lines should instead converge. That's why that box looks so distorted.

I think it's time for you to work through the 250 box challenge. It will significantly help with your ability to draw in perspective, and will reduce the frequency at which you make errors with respect to parallel lines diverging, or converging too fast, present in your perspective exercises.
