Starting with your lines, they are mostly confident, but you correct them at times, making them wobbly.

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 a bit wobbly too. 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.

There are also a few times where you don't draw through ellipses 2 times, always draw through 2 times, not 1and not more than 2.

On boxes I'm pretty sure there are a lot of times where you don't plot your lines. Before drawing any line, you should first draw the starting and ending point of it, to ghost it after.

Line quality in general decreases in boxes. Take the same time you took on your ghosted lines, on each one of the lines of the boxes you make and in general. You should give your best on every mark, it's hard but it will lead to a lot of improvement.

There are also a few instances where you repeat lines. No matter how off a line is, don't repeat it, keep going as if it were correct.

On rough perspective you seem having trouble keeping width lines parallel to horizon and height lines perpendicular to it. I know it's hard but try to be aware of it, it'll get better with practice.

Mostly good job in rotated boxes outside of the line issues previously mentioned, though you have not kept corners between boxes close on this exercise, don't forget to do it.

Lastly I recommend trying more overlaps on organic perspective. 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!
