Heyo, this is a caricature of William Shakespeare that I am working on. It’s my first real attempt at a good sculpt. I may have gone too far with the detail already, don’t know how possible it would be to go back and fix things (if things need fixing).
I am more interested in critique about my sculpting, not about the likeness to William Shakespeare 
I know the hair is not great right now, any ideas?
Here is the main reference image I am working from:
Thanks for any interest/advice!
Oh, and thanks to Ben Simonds for the base mesh!
