Superimposed Lines: Fraying on both ends, make sure to slow down and place your point carefully before you start your line. Fraying on the other end will get better with practice.

Ghosted Lines: There is some curving in some of the lines. Remember to pivot from your shoulder. Curving often comes from your wrist/fingers.

Ghosted Planes: Most of your lines here are confident strokes. There is the occasional wobble, so work on the confidence. Accuracy will come with practice!

Table of Ellipses: You've followed the instructions. Well done keeping the ellipses to 2-3 rounds. As you work on these skills, try to work on spacing and consistent angles.

Funnels: Symmetry is pretty good here along the minor axis. Going forward, try to get your ellipses down to 2 strokes around (3 is fine, but 2 is preferred).

Rough Perspective: With the ghosted lines, remember that the horizontal and vertical lines should run perpendicular to the edges of the paper. If you mess up a line, don't go over it a second time, this just draws attention to the mistake. Take your time to really ghost the lines before committing pen to paper. Accuracy will come with time and practice.

Rotated Boxes: Spacing is good, nice and tight.

Organic Perspective: Remember to add points for your ghosted lines. It will help you keep the length where it needs to be.
