Nice shot but it does look a bit plain - you should close-in just a little, pour some chocolate syrup on it until it runs over onto the white surface, maybe even some caramel sauce for more color and effect. I would also up the contrast slightly, but that's me.
I like this shot, and like the negative space left at the top. My one complaint would be that the lighting seems a bit harsh and is washing out some of the other colors, particularly the red.
