I've been lurking at this board for a little over a year, and have decided to give customizing a shot. Looks like fun, and a bit challenging at the same time.
Right now I want to try and make a custom Doom 2099... However, I'm not sure what would make a good head... I think Dr. Doom's head is a little too medieval looking, not futuristic.
I suggest you sculpt one. Thats probably your best bet to get the correct likeness. I would use Apoxie. Once you get used to working with it, it is fairly easy to use.
