So I just saw that this is supposed to be a spot illustration which I think will be fun! I will probably just include the whole rug that the girl is sitting on and the kids and teacher in the background.
My thought was that she is a little nature lover girl with a bit of a dark side... little twisted, but fun! Might add a small cage below the mouse... It's not the focal point, but i'll bring in contrast to have your eye come to the mouse. Hopefully I get this one submitted, it's farther than January's sketch.
