Here is abit more development into sorting between displacement maps and Bump Maps. Also why I changed between displacement to bump.
I have used Displacement maps a few times but due to this project being short and I want to spend time on other things I have decided to change to bump maps, this would give me so much more time rendering and playing with lighting and other things rather than making sure I leave alot of time to render displacement. Also above shows some of the problems I had trying to render. I had it working but after the redesign no matter what I tried the displacements were causing to many problems and I thought he isn't moving and its not like they are muscles so Bump was called in and below shows my playing with the alpha gain and alpha offset which I learnt that lowing offset and making the gain higher makes the normal maps deeper or lighting so below shows the images of how I developed this.
