EDIT: Hey guys, I now know that Chell can't talk (apparently they say so in Portal 2, but alas I have not played it yet), but if you look at the copyright dates above the artist comments, it says "2008-2011". Which means I drew this several years ago, BEFORE Portal 2 and BEFORE Chell's mute-ness was revealed. So please don't post any more comments saying "Chell can't talk" because I'm getting tired of writing the same answer.
I'm probably gonna re-draw this anyways, there are so many things wrong with it.
Genius indeed. ಠ_ಠ

Sorry for the watermark, but it's gotta be there.
