Initially, I came up with 8 body designs for my Midna redesign. I ended up (as well as the other students) picking the chubby Midna design. I thought it was the most interesting, considering her proportions as the imp.
This piece was 8 more permutations, this time, addressing clothing. I didn't want to lose the concept that she as no human gentials, with the clothes being sort of a formality (after all, she is of another race.) I also didn't want to lose her magic abilites and her hair, both of which sort of get ignored when she turns into True-Form at the end of the game.
