Congratulations on finishing lesson 2, and 250 box challenge as I can tell. Keep up the good work!!

First off, I must say that your work looks pretty good overall. I think got the point of this lesson. But there are some things that I'd like to point out.

Up to organic forms with contour lines, you seem to do a pretty good job. Lines are very crisp, ellipse allignment is very good, contour lines hook on both ends. They look really good. Only thing is that your contour lines seem a bit flat in the middle. You can wrap those around a bit better.

On texture analysis, you did a pretty good job as well. Density transition looks really good, although dark areas are a bit too forward in my opinion, sparse areas could hold more place in my opinion. Also you seem to miss the point that one of the analysis should've been of crumpled paper. I'm not gonna request a revision for this, but I suggest that you do that analysis on your own.

Dissections look pretty good as well, but you could wrap the texture around on some of the forms better (for example octopus rings and slime). You didn't have the same issue with other textures, so I suggest you imply the same thing for these textures as well - use density and contour lines to guide the texture around.

Intersections look pretty good as well. But some cast shadows look like they're sticking out on organic intersections. Wrap the shadow around the form underneath, and you'll be good to go.

As I said, I think your pretty good. And I hope enjoy lessons to come. Good luck with plants!!
