Actually
Looks feminine to me, three things that I don't like are the ear, which seems very small and high up, the way the face is structured through the shading as in it's just not appealing, and the lack of emotion on the face/how the lips are pursed but that is a choice too I suppose.
As far as the style, if you are working in a style inspired by Mucha the linework is a bit too thick around the body, and from the like two things I remember seeing from him which were towards the end of his career, he tended to line in the colors of the fabrics and such with a lot of detail on the face and neck with varying degrees throughout and I think he did a bit more with facial expressions and body language.
Though in general I think you're amazing, this is probably not my favorite but I do see Mucha's style in it so you succeed there, the other reviews are pretty dumb so there's also that
