This reminds me of that Simpsons episode with "EveryMan", except this is books instead of comics. Too bad! I was gonna suggest she touch Garganta's stories or something <:L
Mmm, she be a cute character Mac. Maybe the bashful expressions are kind of overworked rather than coming out naturally from the character, it's a feeling I get. I'm not artist though so I wouldn't know x:
More importantly, does she have a boyfriend? Initially I thought she would be unable to have a good relationship without having to deal with extreme size differences ('lest she was paired with a similar micro), but then you introduced her abilities and, really, she could potentially be anyone's dream mouse.
Anyway, good art.
