Hi MACLENNAN, I'm going to criticize your lesson 1. I'm just going to point out the big problems I found, that is, I'm not going to talk about the exercises that are good.

Tables of ellipses, ellipses in planes and funnels: your ellipses are wobbly. It could be because you do ellipses a little slowly, so increase the speed.

Rough perspective: one of the boxes is extremely crooked.

Organic perspective: you could have done more overlaps and used line weight.

Despite the criticisms, you did lesson 1 very well. I recommend that you do these exercises as a warm-up before drawing.

I marked your lesson as complete.
