I think a slightly faster shutter speed (or slightly dimmer light) would have reduced the blooming around the light and the slight blowout on the sheet music
I like the idea but feel that the light and sheet music are a little blown out and the background is a little busy. The light on the girls face and the piano keys is the nice though :o) (IMHO)
Overblown light and music scores, but we cannot have it all, caan we? Maybe lamp could have been tilted slightly more down, but hey, it's a nice shot anyway.
