For your sake once your done with this guy make something normal, like a average joe, a serial killer, sci/fi guy, a chick, a historically accurate person from the middle ages, something easier to relate to. Something with details that are easy to relate to and there for gage if your good at recreating concepts in to game art. We all know what a persons arm is supposed to look like and what shirts over skin look like so seeing someone recreate that in 3d is great for gaging skill. Its obvious that you can do detail, but doing stylized work at this point isn't much help.
