Concept Art

I received a link to concept artwork for the model I am working with.  This is helpful, since it gives me a little bit of idea of how the character is supposed to move and deform.  Based on this sketches, it seems that sharp angles are important to the design of the character.  For example, the bend at the knees and at the elbows remains pointed, so its important to try and preserve that.  Also noted is the way the pants slide up the leg, revealing the body underneath and the way the stomach bulges in the sitting position.  There are also folds created in the crotch of the pants as they stretch to compensate for the leg being raised and bent.  Another deformation to consider is the back of the head where the skull connects to the neck.  When the head rotates back, there is a slight bulge and crease as the neck compresses.
