3rd Stage Guild Navigator - Revised Design

Well, My Z-Brush skills are getting a little better so decided to tackle the 3rd Stage Guild Navigator... While I was at it, I decided to tweak the design a bit more. In the novel the Navigators are humans mutated through their addiction to the spice melange. The movie creature was interesting and I like the head, but the body basically said "alien" not "mutated human" and since you rarely ever see anything of him other than his head until the folding space scene, I thought that I could "get away" with doing a revision to the original design.

Here is the untextured, un re-topologized version as it currently stands...

I think I may "stretch out" the body a bit... still tinkering with it. Need to add more detail too.
