Dragon Animation!

Here's my dragon flying, I'm getting to be pleased with it, I'd like some feedback though, I'm very very tired. They just moved my shift, today's my first day doing it. I used to go from 5pm to 3am. Now I go from 8pm to 6am. Gah. Anyway, I'm going to render out a version tonight (I've got a 64bit machine here), if anyone makes any suggestions, I'll take them into consideration and update my animation as needs be. I really think I just want to see how fast he renders...
