Looks like you rushed through a lot of it. Take your time.

The lines look better.

When drawing ellipses ghost them where you want to place them until confident with the motion then speedily execute the ellipse. From your ellipses it looks like you are favoring confidence and drawing the ellipses slowly. The ellipses are also not drawn through.

For plotted perspective you should be using a ruler or straight edge. Pretty much anything ruler like. The boxes should be drawn through.

Take a blank page and draw random sized ellipses, focus on fast motion and free flowing. ghost random ellipses, then draw them in a fast motion. Don't try and make them accurate, commit to the circular motion when you draw them. Focus on speed and commitment to the motion. Dont try and correct the motion, or go slow. Confident fast motion.

For the rotated boxes, Copy the video lesson, line for line.

Plot al lines, I will ask for more revision

1 page rotated boxes (coppy the video lesson, line for line, plot all lines)

1 page ellipses

1 page free flowing ellipses

Good luck
