I like this shot the best of all in your series. The crisp focus and stop motion work very well. However the side light is a good bit too strong. You could have used a little more fill from the left. Maybe a reflector bouncing in some light coming from the opposite side possibly. Stop motion concepts are hard to get original. I have seen this before, but it works very well in the framework of your assignment. It has a good bit of impact on the viewer, and i know many people have not seen anything like this before. Over all well done. I find shots like these are fun to redo and play with the lighting. When i revisit something on a new day I often come up with things i would not have though of in one long shooting session.
