So you've got some good superimposed lines, first off. The curves are a little wobbly, but they are admittedly a little more difficult, so that's fine for now. Your ghosted lines look nice too, though I see you did miss very slightly a few times, which, again, is normal. You'll get better at it as you practice.

You did a fairly nice job at the tables of ellipses, for the most part. There are a few ellipses that look like you might've slowed down a bit much--I do recommend trying to draw them a little faster. Don't go too fast, of course, but go just quickly enough where you won't run into any wobbling. Of course, ellipses are just tricky to begin with, so again, you'll improve with practice, however you'd like to do so.

Your ellipses in planes look pretty nice. Your ellipses here seem to be much more smooth than before, so keep up the good work. The planes themselves are looking good too, lots of nice straight lines. Your funnels also look pretty nice; it seems at this point you're getting the hang of ellipses. You've done a good job of keeping them properly inside the funnels, although some of them are very slightly off-center--but this is a common mistake, and nothing to really worry about as long as it's not extreme.

Plotted perspective is nice and clean, looks good to me. You drew through your boxes nicely here. Your rough perspective boxes are looking pretty nice too, though there is a LOT of wobbling and stuff going on with the lines themselves. You do wanna try and keep those smooth, but otherwise, you seem to have understood the exercise itself well. The rotated boxes are, of course, very hard to do, and I see quite a few of yours aren't really actually rotated. The drawing itself should be in a roughly circular shape when you're done, and all the boxes should be roughly the same size. You did do a good job at the hatched lines, though, at least. I would keep in mind that, when drawing this, it should be symmetrical both horizontally and vertically. It helped for me--as much as it could, at least.

Finally, your organic perspective boxes are looking okay, but there's a lot of weird angles that kind of makes everything look like gelatin cubes. A couple tips for drawing boxes like this:

1. When you draw the Y shape to begin your box, the center of that Y is the closest corner to your vision. Everything else gets smaller from there due to foreshortening.

2. Foreshortening itself is something to keep in mind here. Your smaller, more distant boxes should have less foreshortening, as you're viewing them from farther away. The larger, closer boxes should have more foreshortening as they are closer to your point of view.

3. Remember when drawing a line, that it is parallel in 3D space to another line on your box. You can use any parallel lines as a guide for drawing a new one.

4. You can place dots to start planning where to draw a corner. You can place as many dots as you need, adjusting their position, until it looks correct. Then you can draw your line.

So you've done a pretty nice job on Lesson 1. Some of your freehand boxes may be a bit off, but that's what the 250 Box Challenge is for, and so that'll give you lots of practice, during which you'll probably discover and develop your own strategies for drawing boxes.

I'm only critiquing the super imposed lines since I've just finished it myself. The start of each of the lines are consistent showing that you took your time to prepare. The lines look great and there's little to no wobbling on each of them. Great work????
