First, I'm gonna be honest here, I did this lesson a while back. I don't know if information has changed since then. I'm returning now that I have supplies.

the dots should not be all at a horizontal angle to each other. The big take of away from this excise is to learn that you need to adjust your canvas so you are always drawing from your shoulder at the most comfortable angle.

I actually drew these with the paper turned. I was drawing at the most comfortable angle for me (bottom left to upper right). I just didn't bother making the lines not parallel.

I would suggest you reread and retry this lesson so you can get the full benefits of it

I think I will redo this lesson since it has been a while. I think I can afford official critiques, too, so I might as well do that before I move on.

Thank you for the critique!
