Original sketch edited for possible badge/tshirt design

So yesterday on the bus, I noticed that you always see those same familiar characters no matter where you are and what bus you're on. The old lady at the front, the loud chav girl in the middle with her phone going off every 5 seconds, the shady guy with his hat down 3/4 way down the bus, etc.. and I was thinking how they would make a good series of illustrations. So heres the first one, the annoying girl!
