Assignment 6 1/2: Shadow Puppets

Here is my progress so far in making a short bit in AE called "Shadow Puppets." The idea is with one camera and one light I can show a kid playing with shadow puppets against the backdrop of this sheet here:
Here are some of the hands I'm using. We've got an alligator:

and a dog:
I have already set up the scene in AE, but I haven't recorded any movement yet to show you. You'll have to wait till next week for that!

All of these files were made in Photoshop using the pen, brush and paint bucket tools. I also have versions of them where the hands are actually separated from the arms so that I can animate them separately in AE. My only worry is that the files are too small and will end up pixely when animating them. I'm planning on using the puppet tool on the hands to make them bend. That way the pinky can move on the "dog" so it can bark and the "jaws" of the alligator can move. All you will see is their shadows, so it doesn't really matter how distorted they end up being.

I'm going to try and find some nice sound effects in the UT sound library once again. The dog should be easy enough, but what does an alligator sound like?
