I had some extra time today, so I decided to practice my Photoshop skills a little. I really enjoyed rendering this. Nothing was scanned for this drawing. Everything you see was drawn directly on the computer. The trick is to try to make it look like it was done outside of the computer. I'm experimenting more with layers now. For his ears, I used a scan of the skin on my hand (and then turned it into a texture) to get the wrinkles and the fleshy color. For his fur I did the same thing using a scan of a furry duster we had laying around. I then tinted the fur to get the rat fur color correct.
Don't know why I drew a rat. I guess I was just in a "ratty" mood.
