Yes, I suppose the soft jawline, full lips, rounded eyes, soft pupils, soft iris highlights, and thin nose bridge aren't feminine after all. All that armor bulk and toned body (because what knight wouldn't be toned?) are unexplainable, too.
C'mon, ZSG. I've studied human anatomy for years, I know how to draw a woman. Just because she doesn't have tits the size of basketballs or enough curves to make a racetrack blush doesn't mean she isn't feminine. In actuality, with the size of her shield and how exactly she wields it, she'd most likely be buff as hell.
And a third of her body is obscured by darkness, how can you even come to the conclusion she has a masculine build?
