A comic cover in progress

The humidity has driven me indoors this weekend so I've taken to working on some art obligations.  One of them is for a friend's cover (The Body of Nadia Shakir). I recently got a new Cintiq and there is a bit of a learning curve. I was delighted to discover a felt-tip nib which made drawing feel a little closer to the real paper and pen experience than just a stick on glass. Anyhoo, below is the image I'm working on. This will be my first solo cover. I hope I don't mess it up. Wish me luck!  o_O
