Yes, it is nicely done. Good range of tones against the black. You might try it with a crop of about only half the black on the right side. It should tend to force total concentration on the subject, increasing impact.
Wonderful composition, got this in VB. Unfortunatly the edges came out very sharp/were oversharpened wich is not a bad thing in itself but it brought out a lot of jagged edges and hard colors on something you would expect to be soft. great shot otherwise.
