Hello!

Your lines and ellipses look really good! Some of them (the ellipses in particular) are a bit wobbly though, remember that right now confidence is more important than accuracy: this will come with more practice and time. Ghost as much as you need to before you actually draw the lines and ellipses with confident strokes.

Your perspective exercises are really good! There are a few boxes on the organic perspective exercise that look a little bit off: that's because the parallel lines should converge eventually at some point, but some of the boxes you drew have parallel lines that seem to be diverging. You will see more about that with the 250 box challenge, though. And as for the lineweight, you should add it with just one confident line after you ghosted it several times.

Good work!
