So I have done some work in zbrush now and after receiving feedback from both Leavon and Dave I think there is a lot I could do to improve the model. If I attempted to make these changes in zbrush on the high res however the end result would never be as satisfying as if I went back and edited the base mesh and started the high res from square one. It means more work over this week but I think it is defiantly worth it.

The Zbrush work that shall never be seen.
