I think it might be that her eyes are a bit further apart than the "ideal" human face would have them. But I think it gives her a little more character.
Left eye may be a bit to the left. Nose may need some more shading along the left side and the cheeks could use some more lighting. (all directions (left, right) are from the position of the viewer and artist)
son oeil droit peut être par rapport à la ligne du nez ...les vêtements féminins resteront un mystères pour moi ... pourquoi des bretelles alors qu'elle a un collier et un anneau ? ah oui je sais ce qui est bizarre c'est qu'elle sourit au bras de son frère ... impossible dans une fratrie
her eyes are too far apart possibly, the eye closest to us, on our left, is too far away from the nose? And I think the eye furthest away from us, to our right, needs to be tilted more toward us? Right now I think it's tilting in the wrong direction. I think that's it?

Hope this helps!
You are an awesome artist and I love your work, just wanted to help on the question you stated
