Hello, congrats on completing Lesson 1.

Superimposed linse are smooth, properly lined up at the start, and of a consistent trajectory.

The ghosted lines are confident, and straight.

The lines must be centered in the ghosted planes, maybe it could be better to first draw the corners and then draw the other lines as mentioned in the lesson 1 https://drawabox.com/lesson/1/ghostedplanes.

The table of ellipses and elipses in planes exercises looks good. They’re smooth, rounded, and properly drawn through.

The plotted perspective exercise you seem to have gotten what it is wanted out of it, so it’s all good.

The rough perspective exercise is well done. I have nothing to add.

The rotated boxes exercise looks really good. You have taken the time to add some lineweight/hatching. It’s big, the boxes are snug, and they rotate.

The organic perspective exercise in the first page there are some boxes with the same dimensions. They should be smaller when they are drawn away from the viewer. It generally looks good; you’ve been careful about the foreshortening of your boxes, and that has been essential in communicating their flow.
