Hi overall good job and congrats finishing first lesson :)

Lines

Lines are looking p good overall.

Ellipses

Ellipses are fine too, though they do get a bit wobbly, so don't forget 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.

Boxes

Boxes are looking p good.

Rough perspective good job on keeping horizontal lines parallel and vertical lines perpendicular to the horizon.

In Rotated boxes and organic perspective you missed perspective in some boxes, which completely fine, and nothing to worry about, as you'll work on it in 250 boxes challenge.

Overall good job and keep it up ;)
