Hi overall good job and congrats finishing first lesson :)

Lines

Lines are looking p good overall, though they do get a bit wobbly especially in boxes.

Ellipses

Ellipses are a bit wobbly at times. 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.

Boxes

Boxes are fine too, though your main issue in both rotated boxes and organic perspective is perspective, which is completely normal, as you'll work on it in 250 boxes.

Good luck and keep it up ;)
