few days, (24ish hours) on and off, I'm guessing, the skin, detail, and eyes, are the hardest parts, I setup a base model version, or form, then setup rigging to move body parts around, and or move parts into shapes that make up the images you see in a nut shell. my system isn't very fast, so I some times crash a few times

trying to push my system to make the images
glad ya like it, working on a warewolf male next... I picked up the student version of maya with unreal tournament 2003, going ot see if I can make these into models I can play in game
