Alright, I think I'm about done with the design stage of Beorn, which is great, because I'm also finished with this sketchbook. In the end, going back to the absolute basics of character design really helped figure out his body shape. Square = solidity. Duh.
The final design will probably incorporate elements from a lot of the drawings, which is what usually happens when I go through all this. I think these drawings are more a way of weeding out bad decisions rather than arriving at a final, concrete design.
