First thing I noticed is that your lines in organic forms up to contour lines are a bit wobbly. I see that you fix that in organic intersections and detail work, but paying attention to use your shoulder to make any mark may help with the wobble. Another thing in contour lines, your ellipses seem to flow arbitrarily, and you're missing the contour lines with curves work. I would like to see 1 page each of contour ellipses and contour curves to see where you're at right now before marking this lesson complete.

Your texture work is pretty good. In texture analysis, you're lacking the transition from dense to sparse, and in dissections, you could wrap the texture around the form better in some instances. (Pineapple and cloth wrinkles for example) But nothing major, a good work overall.

I see that you started to tidy up the wobble in form intersections, and it seems that you understand the intersections very well. But it looks like you used some clean-up passes where the forms intersect. I would suggest to you to not worry about the accuracy of those lines. Intersections generally look good unless there is a major mistake, so don't push too hard for perfection.

In organic intersecitons, you seem to put a very good work. You understand how the shadows work, your marks are a lot cleaner. Pretty good paper.

Overall a great work but I'm going to request some extra work on contour lines. I'm sure you improved a lot and it's a very easy homework, so it shouldn't be much of a problem. Keep up the good work!
