This was a project I did for my group of friends to use a long time ago, and now it's public for other people to enjoy too. ^^

File contains the base skin as a .png and a .psd version with some layers for guidance:

The chest fur, eye irises, and tail are on the armor layer for a 3d effect, and the skin itself is in the classic Steve format.

Notes: Swap the color layer from 'Color Dodge' to 'Multiply' in order to create a character with darker fur.
You can also adjust the contrast on the base to accentuate or soften the markings to your liking.
