Dear Fishman,

Overall, it looks ok. I like that you worked really clean. it is no problem that you used the pencil, for the 250 boxes challenge will be useful to have 3 colored pens to help you observe the lines.

Lines

Superimposed lines look overall ok. The Ghosted Lines and Ghosted Planes have common issues. The lines are a little wobbly, try to use the shoulder pivot and ghost a few times before. This are minor issues, they will improve in time as you will use them as warm up exercises.

Ellipses

I can not find big mistakes, all will improve in time, as you will practice them. In the Ellipses in planes, it is important that the Ellipse should touch all the sides of the Plane, some of them did not. Try to be more confident, maybe ghost more.

Boxes

Boxes look pretty good. The exercises look clean and I can see some line improvement. This will help you in the next step.
