Character Design created from a simple random shape as a basis for inspiration

This is my response to a tutorial which taught a technique of character design using a random shape as a guideline and basis of inspiration. I feel this exercise has helped pull me out of creating character faces that are generic and don't have much personality. The tutorial also featured cell shading a technique I had not yet used properly and I have found the results very interesting with much better lighting than a lot of my work  in the past.
