When it comes to lines, I noticed a teeny bit of wobbling in some of your lines. Though they look quite accurate, with no arching.

I noticed a little bit of wobbling in your first ellipses, but you seem to have fixed that in later exercises. Your tables of ellipses look nice. You stayed within bounds and they only just touch without overlapping.

You made an important mistake in your rough perspective homework. With a different colour pen you were supposed to continue your depth lines to the horizon, not draw a line to the vanishing point. Here's what Uncomfortable says, "Once you're done a whole page, grab a pen of a different colour, or a pencil, or something you can visibly separate from the rest of your work. Using a ruler, take all of your depth lines (those that are meant to converge towards the vanishing point) and extend them to where they intersect with the horizon.

We are not plotting these red lines back to the VP - just to the horizon line. This will show us a concrete idea of how far off we were."
