Lines and ellipses are pretty confident. On tables of ellipses, don't overlap the ellipses. They should only touch each other. I recommend also only drawing 2 times through each ellipse.

There's an issue you do in lines, and that is repeating them, no matter how off a line is, don't repeat it, keep going as if it was correct.

On plotted perspective, you should have used the ruler all the way through, even if that made the drawing less clear, as instructed.

In rough perspective, you have again problems with repeating lines, and struggle a bit with height and width lines. Remember those should be vertical and parallel to the horizon line respectedly. They are hard to get right, but be sure you're aiming for it.

On organic perspective, apart from what I've already said on lines, I recommend trying more overlaps. You can clarify after the overlaps by adding a confident, drawn with the shoulder superimposed line. Perspective on them has issues but you'll work on it on the box challenge, so don't worry about it!
