upper arms/thighs too short (if there are knees/elbows at all), torso too long (does she even have hips/bendable midriff?) does she even have a neck?
I don't really get the point of making any kind of alternate version of Juni, since her anatomy only works in that tiny-pixel-scale, and trying to translate it closely to anything else is kinda pointless. and if you don't stay too close to the original, then you could just look for a render of any possibly meant-to-be-female and put a white nightshirt on it and black hair. or something?
