Nice art, definitely. I love that you kept the absurdly oversized hands despite her otherwise slender form.
However, the whole genderbent Xerath irks me. "Male Xerath" has no discernible form beneath his chains (aside from the hands) and in his lore he has evolved beyond physical form. When he uses his taunt, he is merely a blue stick figure in armor - there's nothing technically "male" about his appearance. And yet all the "female Xerath" artwork has invented a naked blue chick. Is there actually no "tasteful" way to make Xerath identifiable as female without simply putting a woman inside his "armor"?
I wouldn't say traditional is better - traditional is just a fancy word for unoriginal. Form just allows for the go-to landmark to "prove" a character is female - i.e. breasts. I'm not surprised—females in fantasy artwork is almost always sexualized—I was just curious about how you could make it less naked-chick-in-armor and more "Xerath". More feminine armor would probably do it.
