Lines start a bit wobbly, and they improve a lot in terms of confidence, but they still have a tiny bit of wobble at times.

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 have a bit of wobble too, but mostly they're pretty confident, remember here as well confidence > accuracy always.

You're missing the funnel exercise. So reply it to this comment if you want me to go over it.

Boxes look good in general but you're repeating lines. Remember, don't repeat any line no matter how wrong it is.

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!
