New site for my birds

Ok. You Dribbblers get the first look:
http://www.noproblemnigel.co.uk/birds/

I like to dabble with code from time to time, this little project was just for fun and has been keeping me entertained for the past few weeks. I understand I'd lose quite a few limbs if I came face to face with a real CSS Ninja.

Would be rad to hear what you guys think and how I could improve the site?
