[Help] I'm a female, 5'5" and about 115 lbs. Any Cosplay Suggestions?

As stated in the title, I'm female, 5'5" and about 115 lbs. [Here](http://i625.photobucket.com/albums/tt333/campbellsouplauren/IMG_4233_zps1e0a9137.jpg) is a picture of one of my recent cosplays (as Chell from Portal).

I prefer athletic characters (more fun to pose!), but am looking for any character that fits my build and is relatively simple to cosplay. I'm open to anime, manga, video games, American cartoons - anything goes.

Any advice or suggestions on characters I could cosplay as?

edit: These are some pretty awesome ideas. Faith from Mirror's Edge looks like the most fun. Thank you!
