Hi! i'll critique your homework. English is not my native language, so sorry for that in advance.

First of all, congratulations on finishing and submitting your first Lesson. Overall you done a preety decent job there, it shows that you read the lessons and follow the rules for every exercise. With that said, let's move on into the details.

Lines

Keep on ghosting your lines! never forget to do that, even if you' re hesitating for the next stroke. Also, it shows that you're drawing from your shoulder, but keep that in mind, don't forget it. Marking the dots for your strokes also is a good resource, keep it that way.

There's some woobles lines present in whole exercises, but that it's something that you'll improve as moving on.

ellipses

Ellipses are tough, specially when you've nver draw seriously before (like me a couple of months ago). Don't keep them aside, you're doing a perfect work not drawing through them more than 3 times. They could be pretty, but it shows understating. in them. You should try to think of the space that is using the ellipse and how interacts with the others (i see some blank spaces on funnels, you should draw it next to each other)

Boxes

Congrats on finishing your rotated boxes! They're no actually rotating ahhaa but it shows that you try. Mind on the deep of the rotation, like if the plane of the paper is represented by the X and Y axis, the Z axis shows the closeness to the viewer of that plane (hope i express that well, if don't, tell me).

The same for the organic perspective: the boxes arent rotating and they're not getting far away or closer to the viewer (well, some of them are, but not everyone).

On rough persepective, the closest edge of the boxes to the viewer must be perpendicular to the horizon line. Keep that on mind, but it shows that you're trying.

Well, like i said before, you did a nice job doing this exercise. Feel free to move on and tackle that 250 boxes. Remember to ghosting your lines and keep this exercises in mind (you SHOULD do at least 15 minutes of warm up before every session of drawing for this lessons. The warm up exercises are ghost plane, funnelss, etc) Hope will see you submitting again :)

Laslas.
