Okay, I really like seeing that you are experimenting with the exercise and I think that you are really close, though I want you to check out this correction and compare it with your exercise. While your forms are wrapping more convincingly to each other and feel more solid, they are not wrapping around the silhouette. Remember that in order for a sausage to go over the other side and stop being visible for us (even though we have to draw through all of our forms), it needs to be behind something, and in the case of this sausages it needs to wrap all around the form, and it starts falling to the other side, once it's over the silhouette.

I've highlighted just the 3 forms that directly fall on top of the big base form because the more top one depend on how this first ones position themselves. Notice that you just need to draw them a little higher so they match the silhouette!

Regarding cast shadows, they are much better, though don't worry if you can't exactly realize how the cast shadows fall on form, this is something you will practice more with shading.

So, one more page, I don't wanna say it's the last since I kind of jinxed it last time, but I feel positive that you are getting close.

Go get it.
