It's not from an anime. I found during a long, long, long search on google. It was unfinished and such, so I "shopped", polished and straightened it out. If she is from an anime, then I don't know which one she's from. But I'm pretty sure she can play guitar pretty well...
It would be terrible if there was cup ramen right next to you and you couldn't decide wether or not you got up to eat it or to just sit and stare at it...
