I like Amanda Conner's artwork and was told about this on YouTube. It is from Amanda Conner, Jimmy Palmiotti, and Garth Ennis. It's called The Pro. It was a graphic novel about a prostitute that gets super powers, but is TOTALLY tongue in cheek and makes fun of comics at the same time.
Watch this shit for a great laugh! It actually made me buy the graphic novel, which is slightly different, but very close.
