Though something I did awhile ago I figured I would upload something showing the work I did on the fox Kerribek!
The image on the left is the original head and textures, the right is after the work I did creating a new one.
Original textures were my guide but I created my own fur and shading, each little lighter fur was hand done with a photoshop tool to make sure there was a good flow to the fur. All in all the textures for the head, jaw, and ears took about....8 or 9 hours I believe due to all the layering that went in and individually drawn fur.
