How I did the fur in [link]Note: I'm working in SAI
1.) Base is a dark shade of the fur color that is used.
2.) Made fur-like brush strokes with a med-large sized brush with my fur color. The length of the brush strokes depends on where on the body you're at. Small, short strokes for shorter fur, and larger/longer stokes for longer fur. Study your animal's fur pattern to determine how it's layed out.
3.) With a smaller brush, I did wispy outlines on the ends of each of the larger brush strokes to make it look like actual fur.
4.) Added wispy highlights and shading wherever necessary, depending on where my light source is.
That's about it
I just realized it's a Tribble....
