Yes, I agree that working in black and white should be the foundation of any 2D piece. I have seen it many times in alot of really great digital paintings. Black and white for a 3D piece is a bit harder. Lighting is the key to 3D in my opinion. I'm hoping the color textures wont take away but emphasize the monochrome effect. In doing that I'm not going to make the textures very bright. They will be on the grungy side. Dark is the key to this model, but just enought light to catch the color and detail.
