Hello,

Lines:

Looks like you like to grind new skills :D You also have confidence in your lines and know how to do ghosting lines.

Ellipses:

No noticeable issues (apart from leaks from your ballpoint pen), just grind it more during warm ups.

Boxes:

Looks like you got some problems with rotated boxes exercise, i suggest to rewatch the lesson, or the some kind of cuboid and rotate it in one dimension e.g. along the y-axis. if not there is useful animation https://drawabox.com/lesson/1/17/rotation

Organic Perspective looks good, but more less from the middle of the distance boxes stop growing.

This three section may be useful for you (for future challenge) too:

Btw, consider buying dark ink pen like the dude who created this whole course suggested. Easier to watch your submission and you will avoid ink leaks on your paper.
