Overall this lesson is done quite well! good job

I wanna note that your ellipses need to be confident, smooth, and evenly shaped, and while this isn't an issue throughout, I noticed this come up during your table of ellipses/ellipses in boxes exercise and rarely in your funnels. However, this is only a rare issue, so no re-dos, just keep an eye on that for yourself.

In rotated boxes, remember we don't want to hatch the outer most corner boxes fully, just the inside planes where they come towards the middle. Remember we also want to keep the gaps between our boxes narrow and consistent. This is a very strong attempt for a very hard exercise though, so good job.

Another thing I wanted to note and yes I'm aware you mentioned this in the description is the excess lines and the crossing out. While you are already aware of this, I'd personally recommend some drawings you keep to yourself where you draw badly on purpose, just to help lower your standards and let you relax more, because drawing and repeating lines in future lessons will make it significantly harder for us to critique. Having the confidence to let yourself make mistakes is far more important than you'd ever expect.
