Hi there! I think you're doing a p good job but I want to go over the issues I find, so you can keep improving, into it!:

You're only doing this mistake ever so slightly, but I want to point it out nevertheless, as it's pretty important:

In these exercises, you should always prioritize confidence over accuracy.

A wobbly line will always be worse than a confident line, no matter how off the confident line is.

If you take a look over the ghosted lines notes you'll see the levels of lines:

Level 1: Line is smooth and consistent without any visible wobbling, but doesn't quite pass through A or B, due to not following the right trajectory. It's a straight shot, but misses the mark a bit. Level 2: Line is straight, smooth and consistent without any wobbling and maintains the correct trajectory. It does however either fall short or overshoot one or both points. Level 3: Line is straight, smooth, consistent without any wobbling. It also starts right at one point and ends exactly at the other.

As you can see, wobbly lines aren't mentioned, which means that they would be worse than level 1.

Ellipses are here as well a bit wobbly. Remember that in ellipses as well as lines you should try to do them as confident as you can, don't hesitate in sacrificing accuracy to get them smoother and more confident.

In boxes there are a few issues. First one is the same as before, lines are a bit wobbly, so careful with that.

Next is that on rotated boxes, some of your boxes weren't actually rotating, careful with that, this mistake is explained here.

You are repeating some lines as well, no matter how off a line is, don't repeat it, keep going as if the lines were correct.

I recommend trying more overlaps on organic perspective as well. 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!
