This one is pretty obvious in the way she has pigtails going on and the color scheme is easily changed to whatever style. The most popular ones being black/red.
I would also suggest a change to her primary skill. Id give it some form of elemental damage. Basic damage is good, but it gives an extra oomf when doing it. Unless her gold skill will work with it, then never mind.
I do want to edit an image of Artemis when i have a chance to get that color scheme going.
