Hi overall good job and congrats finishing first lesson :)

Lines

Lines are lookinggood overall, though you have some long ones that are arching a bit. This can happen because you might not be using your shoulder as your main pivot so check you're doing it. Another thing that can help to fix this is to try to arch consciously to the the opposite side when drawing the lines.

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.

Also good job on funnels(minor axis cuts ellipses in halves).

Boxes

On boxes I can see you're repeating a lot of lines. No matter how off a line is, don't repeat it as it'll make the drawing messier.

In rotated boxes and organic perspective you missed perspective in some boxes, which is completely fine, as you'll work on it in 250 boxes challenge.

Good job overall. Be specially careful about the repetition of lines as it's something you're doing a lot, as well as the wobbly lines that you sometimes do.
