Hi! i'll critique your lesson 1, congratulations on your first submit!

lines

You show a little wobbling on the firsts exercise, but you're getting the idea. Remember always plot your lines, ghost them, and then draw from your shoulder.

Good work on not repeating your lines on ghosted planes.

Ellipses

you got the whole idea of how a ellipse works. Kudos for that. Notice on keep the boundaries in table for ellipses. Remember to keep in mind the minor axis in general (on funnels, some of them are not alligned)

Boxes

You should to re-read the box section, and as you move on, read the 250 box challenge very carefully. Your boxes are good enough, but you can do better. You have to hatch the nearest face to the viewer of the box on Plotted perspective. In rough perspective, the boxes corners should be perpendicular to the horizon line. (also, you show a lot of wobbling in this exercise, remember to plot, ghost and then confidently draw from your shoulder).

Kudos on completing the rotated boxes, that is one of the toughest ((?)don't know how to spell it) exercises on lesson 1. You did an amazing job there!

On organic perspective, you lines seems to be arching on some boxes, work on that as the instructions says (https://drawabox.com/lesson/1/9/arc) I suggest to redo this exercise, before you move on onto the 250 boxes challenge.

With alll that said, i think you get the whole idea. I'll mark this lesson as complete, but keep in mind this critique to work on that points and improve your drawing.

Laslas.
