Given all the flack that has occurred regarding that thrice-damned MJ statue, I now present you with a picture of a good one:

Notice the subtle blending of sexy and kickass. Note how she is standing in a position of strength, yet still provides eye-candy for the boys.
Notice how the focal point of the statue isn't on her breasts, but on her eyes and her weapon.
Notice how she's actually wearing less than MJ, but is taken far more seriously.
EDIT: Eris take me, I have finally succumbed to the LOLCat phenomenon:

Go here if you don't get the joke.
