Nice work with the arrows, not much to say about it, just keep practicing.

Contour lines and ellipses are incomplete, you still need to send the contour lines page. But the ellipses page are nice, good work with the degrees of the ellipses.

You forgot to send texture analysis page.

Great work with dissections, just try to avoid using lines, you still used sometimes.

One page of intersections needed to be only with boxes, good work but various intersections are wrong, try to take your time to think about how each form intersects.

Good work on organic intersections.

Nice work. Just submit the missing pages and you are ready to lesson 3 :)
