She's combine assassin from half-life 2. Unfortunatly, you couldn't see her in the game: she was only in beta. One thing for sure: she's got very good body, but obviously it was hard to "port" it into blocky minecraft character. But, here is result. I hope you like it, and don't be too harsh please: this is my second skin and I'm still learning about doing them.
Edit.
I have fixed her "backside". It looked like it was transparent, so I recolored and changed it so it looks better.
