Let it all hang out?

A good friend of mine and fellow housemate Ben, has asked me to design a flyer and poster for his upcoming dub/funk/soul night, held at Leeds' Northern Monkey. He wants something memorable and bold, with suggestive use of a female as part of the imagery and minimal colours to keep costs down, also the job has to be done quick, with a mon/tues deadline (3-4 days).
This is great as its a real challenge, here's some initial ideas concerning the imagery and composition.
