A question about the character artist role: do you need someone to create a character model, texture it, create clothing, rig it and animate it by themselves? Often someone does the work on the model while someone else specialises in the animation and rigging. Obviously you have less people working on an indie game, which is the reason you don't often see realistic 3D characters. You could go with characters made with something like CC3 to save some work, but you'd still need an animator.
