I liked Rebootking's "Space Man" concept, so I retoped to a mesh that you could texuturize and rig it. At12000 poly's it is still a little high, but kept as much of the orignal shape as I could. Rebootkings mesh had too many intersecting faces to use further, nice for a concept mesh, but not to texurize or rig.
The images are 2 k raw TGA's hence the size. I left them as raw so you could continue playing with texture painting. Could have went on for hours painting. I was able to get 1000x more detail painting without having to add more poly's. You can always up the poly's with mutli-res and scuplt some more or retope and reduce to a simple mesh for BGE or Unity.
Rigged it with Rigify. Has a simple walk animation. Camera spins. Cool dual shadow lighting that looks quite natural.
