I really love the colours. Do you have a link to a less compressed version? The Jpegging played havok with the smoothness and I'd love to get a better look.
Oddly enough, the colour seems to be a bit leached out - it's a virulent tourquoise and red - almost like M27 colours - on my CS3 screen.
The star colours are washed out too - I'll see if I can correct that
