Hi! I'll be critiquing your lesson 1 with help from the official critique guide and Elodin's critique guide.

Lines

Starting with lines, your lines look confident overall. There doesn't seem to be many signs of wobbling, and most of your lines are accurate. Although some of your lines do seem to be arching especially in the Ghosted Lines exercise, you'll get more used drawing with your shoulder as you do more of the Drawabox exercises, warming up, and according to Elodin's guide "it can be fixed by trying to arch consciously to the opposite direction". On your boxes exercises and one of your lines in the Ghosted lines exercise, I see some repeating lines, which you generally want to avoid if you aren't trying to add line weight. If see that your line is off, it's best to keep the line as is and move on. On the Ghosted planes exercises, you forgot to bisect the plane by adding a cross through the center of the X (https://imgur.com/a/RyZTNbd), so next time you do this exercise remember to do that.

Ellipses

The main thing you should focus on in the Ellipses in planes is making the ellipse big enough to touch all 4 borders (https://imgur.com/a/gu7IapM), but other than than that, you're ellipses seem both confident and smooth. One thing I would recommend when doing the Funnels exercise next time is trying to Increase the degree of your ellipses as you move outward (https://imgur.com/a/9HW0RLT), since that will help with the future lessons, but if you don't feel comfortable with that yet it's fine, since it is optional.

Boxes

Plotted Perspective: Looks perfect

Rough Perspective: On this exercise, you did a good job trying to keep the back shape consistent to the front. Not sure if you're already doing this, but something that is also recommended is using the horizon line as a reference helps keep your lines parallel and perpendicular.

Rotated Boxes: All your boxes seem to be rotating to a certain extent. Remember to keep your gaps even (https://d15v304a6xpq4b.cloudfront.net/lesson_images/9a16c189.jpg)

Organic perspective: On some sections of this exercise, the boxes aren't rotating as much as they should be. The lines on the Y shape doesn't have to exactly look like a Y. You can shorten/lengthen some parts of the Y shape, make it the Y shape upside down, or making parts of it wider/narrower (something like this https://imgur.com/a/zidQJHM). Your boxes do look good though and they will get better as you do the 250 box challenge.
