1- here you have the line art.
2- now you see the flat color.
3- I'd just removed the flat colors so I can concentrate on the first cell-shading layer
4- now I added the second layer of cell-shading.
5- I decided to add a third layer.
6- now you get all the cell-shading layers with with the fat colors.
7- and finally, I used the air brush to make the final touches on the fur which are the silver highlights.

I know is not the best method but this is how I do it.
For those that are just staring cell-shading fur... It kinda feels like you're drawing leaves.

One more thing! if your character is black or any other dark color... You might want to just use 2 layers of cell shading
the third layer kinda got lost in the darkness
