1. Superimposed Lines: Fraying is accepted to some degree, but there should be more accuracy, especially when drawing shorter lines. The lines on the second page are better, though. When I did this exercise, I was aiming for accurate short lines(one over another), fraying ideally more towards the last 1/3 of the line and getting as little fraying as possible when drawing longer lines(at least get the first 1/3 of the line to be a common line).

2. Ghosted Lines: Good job! You got it. When I did this exercise, I was trying to use my shoulder as much as possible. Getting a confident line is more important than getting an accurate one. You get better at both, in time. Straight, confident lines, your priority!

3. Ghosted Planes: You did great, as far as my understanding goes. Nothing much going on here, this exercise is about practicing the ghosting method more.

4. Tables of Ellipses: There is some degree of wobbliness to your ellipses. You aren't using your muscle memory to the fullest. This is also present in the ellipses in planes exercise, so you should pay more attention to it. Take your time and apply the ghosting method before drawing the ellipse. This is why the ghosting method is important, it lets you get as close as possbile to drawing the desired line. Practice this exercise more!

5. Funnels: Pretty much the same thing as in the tables of ellipses exercise. I won't say too much about this one, because I messed it up a little bit. You should aim for symmetry here. Draw the ellipse as symmetric as possible.

6. Ellipses in Planes: Again, you should prioritize drawing confident ellipses over accurate ones. I guess you tryed to get the ellipse to fit as perfectly as possible in the plane, but this comes after you eliminate the wobbliness.

7. Plotted Perspective: Not so easy to give feedback on this one, as I cannot show you specific things. You got the idea though, it seems okay.

8. Rough Perspective: You did better than me when I tryed it for the first time. More practice!

9. Rotated Boxes: You are getting a little bit off in this exercise. Maybe you should try to do it again. This time aim for a more rounded shape. This is an exercise I'm also considering to do again, as I couldn't draw through the box well enough when I first tryed it. Your straight lines are more confident than the rounded ones(I mean the ellipses). You are supposed to draw a ball made out of boxes. That's definitely harder than drawing a box made out of boxes.

10. Organic Perspective: This exercise should be done again. Have at least 3 frames on each page. Draw more boxes, it's for your own practice. Also, you should aim for getting better at visualizing the box in your head, playing with it in your head, rotating it. Asking yourself where this line would be, how convergent would it be, where this edge would be, how would I draw it, and so on. Whenever you are bored, try this.

Exercises to consider doing again: 4, 9

Keep it up! Have fun and be safe.
