I'm not normally a fan of flash-based sites, but this I actually quite like
It's simple, loads quick (at least on my machine) and is easy to navigate. Personally I would be inclined to leave the music off by default and let the user choose to turn it on. Automatic music often seems to irritate people on websites, particularly if they're already listening to something of their own - although the music you have chosen provides a nice atmosphere.
My only other criticism would be that the gallery doesn't re-size for a display of 1024x768 (on firefox, haven't tried on IE). Most people are probably on 1280x1024 now, but some laptop users may not be, and it could lose you some interest.
Some lovely pics too!
