Hi Guys.
I got myself a wacom intuos 4 a couple of months ago and have spent a bit of time playing about with it. Now I'm trying to start to get a portfolio of good works together. I have been working on this piece for a few evenings now and I'm not sure what to do next, I have tried to keep the focus on the upper torso. Any advice or criticism would be much appreciated.

New to digital painting. Looking for pointers.
