It is a little known fact that pretty men are very territorial creatures, with many willing to scratch the eyes of opponents out with their perfectly manicured nails in... Well, a blink of an eye. This instinct and desire to be the most asthetically pleasing male person around is heightened to extremes when they are threatened by a potential usurper who's features are similar, blonde locks, for instance, and fan girl attention is equally high...
The colour version. I decided against drawing a 'bitch fight'... I did start one off, but it just went on a bit and got a bit tedious/cliched, I'm afraid.
