this is the best of the three that you've done. let me explain why. You're very good in terms of shading and color. but one thing that's bothered me about this character from the start is if you look just at her face, its difficult to see its a she. this is one of the few where here face looks female.
She just has a round face and thicker eyebrows in the other pictures, in this one her chin is more pointy and her nose isn't that pronounced. In reallife you will see more girls with the former face shapes. It may not be what all the different media portrait as feminine but whatevs.
she looks mad
Besides her awkward pose, this is really good!
Yeah she should probably bend her back more in this kinda motion.
