Well here is a little something I did in my sketchbook with ink (and slightly shaded in pencil). I put it into Photoshop and colored the sketch. This is my mouse character from the Transformice game.
I really had a fun time doing this and wanted to make her more mouseish that I have in the past (where it turned out more rattish) while still keeping the TFM style.
