Congratulations on finishing lesson 1!

Lines:

I like a lot your ghosted lines and planes, they are very confident and have little to no arcing. Your superimposed lines look wobblier overall, but that's not an issue I see you repeating much after this, what you do seem to be repeating is not takin the time to carefully position your pen over the starting dot (as evidenced by the fraying on the starting side).

Elipses:

Your elipses are noticeably wobblier. I'm guessing you did this because you were trying to make them fit their container. In the future try to aim for fluidity over accuracy, accuracy will come with time

Boxes:

You have some perspective issues, such as in your rotating boxes exercise some boxes are not actually rotating, but aside from that there's just one big issue I see. Some of your boxes are either chicken scratched or redrawn to cover up mistakes. Regardless, you should avoid doing both, chicken scratching would be a bigger issue since that would mean you're not applying what you learnt in the Lines sublesson to these exercises. Redrawing is also an issue, but not as major. When you try to redraw over your mistakes you end up drawing more attention towards them as well as not allowing yourself to review what mistakes you made. As you move on to the 250 box challenge avoid doing that as much as you can, reviewing past mistakes is a big part of that challenge.

Aside from that, I just wanted to tell you a few words on the subject of failure. After reading more of the material from Uncomfortable I've come to understand just how important failure is. Success may feel good, but you never learn anything from it. If you want to get good, the fastest way is making a lot of mistakes and learning from them, which I think is what Unconfortable is going for with the 50/50 rule (Which I hope you've been following) and the exercises where you're expected to fail. Don't get discouraged, just keep going and appreciate your failures.
