Hey,

Starting with your lines, you're mostly doing a good job, though they arched from time to time: Arched lines usually means you arent using your shoulders.

Ellipses

Ellipses are good. There are instances where it wobbles but not alot which means you are pioritizing accuracy over confidence. Although keep in mind 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. Other than that looking pretty good.

Boxes

Your rotated box are great.

On organic perspective your boxes have perspective issues but you'll work on them on the box challenge, so no worries.
