Finally managed to get my head around creating displacement maps. Took me about two days of tinkering around to finally get this looking acceptable, had lots of fun though and I definetly learned a lot of good stuff. I will definetly be implementing ZBrush more into my workflow from now on, such an amazing program. Anyway below is the result of my toiling, all that is left now is painting the texture:

Also, I was curious, are we allowed to implement reflectivity into our material?
Any crits are very much encouraged, I really want to hear suggestions for how you guys think this might be improved more.
