If you want something that's not too long, you could try a couple of the easier Chopin preludes. I don't remember which offhand are which, but maybe Gm if that's the one I'm thinking of.

Just a thought.

If you want something that just sounds pretty to play in front of people, check out Big My Secret or The Heart Asks Pleasure First by Michael Nyman (from the movie Piano).
