Making Liquorice proof, feedback needed.

First proof and I need some help. It is meant to be the horse on the right and is for my sister and the owner, so no pressure! The mane seems too busy and in a different style to the forelock plus it is white, as is part of his forelock. Do I thin the lines down mre or get rid of some or what? Any feedback gratefully recieved. This is the first time I've tried to actually make one look like something real. Image is 4 inches high
