Dancing Queen

My character Yasmina again (yes, I have to admit I'm very fond of her ), this time in her dancer's garb. As her path as a Rogue ended in prison, she thought it would be nice to pursue a more....legal...carreer. Her dancing skills will also prove very handy once she is a Derwish (some kind of war dancer) - but she doesn't know that yet. Dancing is one of the rare occasions she doesn't wear her hair in a braid, but lets it flow past her shoulders - complete with carefully attached bead strings.
The lips on her rear are a tattoo - it's the symbol of Sharess, the goddess she worships.

I've been thinking about it a lot and came to the conclusion this picture actually needed a background. However, I couldn't really come up with any good ideas. So, what do you think would be a fitting background?
