Animation - Base Fingers

I decided to mess around with animating something small, since I'm trying to get used to it so that I can animate an intro for my YouTube channel. I tried to do hair waving in the wind at first, but that wasn't terribly good. So I took something else I'm working on, and used that. I kept it simple, doing nothing but waggling some fingers back and forth. It worked

Anyway, after I practice a bit more, it's on to trying to find a decent animating program. All of the free ones I've downloaded are missing vital features, so they unfortunately won't work.
