Your site is very nice and a bit different than the usual, probably because of the Flash. Your Flash is not at all annoying, as it can be on other sites that use it. (A web designer friend of mine told me that they call it "Shoot the duck!)
Your girlfriend did a great job!
I listened to a few of the pieces and heard a only few minor glitches, but I don't think anyone but a classical guitarist would notice them. Even then, they are nothing to worry about.
If you put your website in your profile, it will follow you around Delcamp as a little globe beneath your avatar each time you post.
