Diana looks like she's in her early teens here. That's an interesting take on her. We normally don't see her looking this young, and one could come up with an interesting story of her youth and her training from this image.
Well, it wasn't my intention to make her look young, but I guess it kind of turned out that way with her innocent expression and roundish face. That does sound like a cool story idea, though.
Looks amazing, love her pose, hair and eyes.
