colour doodling

I'm in desperate need of practice drawing backgrounds and using colour, so this evening I did some work on this digital painting I've had on the back burner for a while. I like the general light/dark contrast, but I'm not really happy with the colour yet (especially the girl). Maybe I'll look up some reference photos.
