I got a few more questions privately, so I'm posting them:

Q: What are you modelling in?
A: 3DS Max 8, except for some reason I did the ear in Maya 7. Some additional refinement in ZBrush.

Q: It looks like there are tris in there...
A: Not in those pics. That's one sub-D down so all tris are now three quads, actually. In the low poly mesh there are some, but tris are only a problem when they cluster together. They are spaced out. Look at the face wireframe and you'll see that deliberate effort to keep them pretty evenly spaced (based on the quad-triplet triangles that you can see) has been made.

Q: So there's a low-poly version too?
A: Well, of course. That's how it gets modelled. If and when I release the low-poly versions of figures, and if those versions are free is not determined, so I'm not talking about it here. Shaddup.

Q: That render looks cool. How did you do it?
A: Just the Max 8 default scanline renderer with Advanced Lighting->Light Tracer turned on and a single Skylight with default values. The floor box is added to make the render a bit nicer than Sar just floatin' in space there, and to provide a bit of radiosity back up on Sar, as the Light Tracer does that. Takes a little longer than a default mesh render without any lights (about three times as long, or twice as long as an unlit Mental Ray render) but looks nicer when showing something off.

I'm the asshole. You wanna be a shit? You gotta go through ME.
