Congratulations on completing lesson 1! Here's some feedback.

Lines

Many of your lines look really confident, including the curved ones. It seems like you might strugle a bit with longer lines wobbling, so be sure to practice those in warmups.

Ellipses

The table of ellipses looks lovely! Really clean and confident, and a good variety. Like the lines, there is a bit of difficulty when you do larger ellipses, so this might be good to include in warmups as well. There are some slightly pointy or egg shaped ellipses in the "ellipses in planes," but also a bunch that work well.

Boxes

Plotted perspective: looks good. A few diagonals, and one missing line in the middle panel, but you clearly understand this just fine.

Rough perspective: While that first panel has some diagonals that should be horizontal and vertical, it looks like you corrected this by the end. There's a lot of improvement over the course of this, including in the convergences.

Rotated boxes: Looks great!

Organic perspective: This is a great start! It seems there is a page missing. I'm guessing you did it, but that it didn't make it into the upload. Given the improvement I saw on the other pages, I'd like to see what page 2 looks like. There are a few diverging lines, but you'll work on that in the 250 box challenge. Also, the size of the boxes doesn't gradually shrink or grow as they travel through the thread. One way to manage that is to shrink or grow the very first line you put down with each box, then go from there.
