360° Head Animation

I've been hooked by some YouTube Animations created by some of the most talented animators and decided to take a shot for some practice in my spare time. So this is a 360° rotation of my head by 8 frames with a repeating loop.
This was my first try: http://tinyurl.com/o73qe2e

I wont add more frames for a smoothy animation, because I decided it is more important
to get it done allready! :/

I hope, soon I'll be able to publish my own animations!
Damn, all that stuff took so much time!
Let me know what you think.
