In your lines, you've parts where you are focusing on confidence, but you have a lot of wobbly parts too.

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 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.

You're also not drawing through ellipses. Remember you should always draw 2 through ellipses in drawabox. Don't forget it.

In boxes you seem to be rushing a bit. Take your time with each mark you do, don't rushing.

In rough perspective all width lines should be parallel to horizon and all height lines perpendicular to it. Don't forget to aim for it.

You're also repeating quite a bit of lines. Don't forget you shouldn't repeat a line no matter how wrong it is, always keep going as if it were correct.

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

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 on the part of the silhouette of the boxes that overlap. Perspective on them has issues but you'll work on it on the box challenge, so don't worry about it!
