Your 3D model work is beautiful, I'm currently learning maya and having trouble wondering if i'll ever get to this sort of level. And yes 3D printing I had to do quite a bit of rapid prototyping on architecture models with them and the prints are stupidly expensive :S £90 for 30cm3. If you ever do get to printing one just make sure no section is less that 1,5 mm wide or the superglue they dip it in will warp the figure quite badly - its a little scary the amount of heat produced and seeing your model steam whilst it hardens.
Thanx BadbrushArt, I only used Maya for rendering this model and to be honest it was a pain. I've since discovered Keyshot which renders pretty well for beauty shots. I'm not much of a 3D modeler, I'm more of a sculptor (only recently learned the difference). Maya is ok for creating base meshes which you can easily do with zspheres or Dynamesh in ZBrush. If you just want to sculpt and quickly get ideas down, i'd stick with ZBrush for now. Just my two cents.
