Thanks a lot for the feedback, Ennuiwolf.
The undershooting has been a pretty consistent problem for me. I think your advice is spot-on: I'm drawing lines at a slower speed than I am capable of right now.
I did not know there was a recommended amount of times to ghost or else forgot! 3-5 times: I'll be doing that going forward.
As for drawing over lines... it's never a good idea. It got particularly bad in the rotated boxes exercise: there may have been more redrawn lines than original ones. I'll exercise my willpower to prevent myself from redrawing a foregone line in the future.
Your review was very helpful and well-thought-out. It also comforted me quite a bit as I was halfway sure I had done the lesson poorly.
