I am superglad that I opened the highres and could see all the fur textures and how well the follow the body. Top notch and I would love to know how you did that!
In regards to the image I like the charecter and the pose as it gives a sense of movement, i.e. that she's flying through the air. I just wish that her left foot had been a bit more angled towards the center of the piece to change her direction more towards us. I guess that means angling the foot down to the left. Otherwise the anatomy and style of the piece looks great. The only thing I'd like to see improved are the teeth as they look a bit wonky at the moment, but as I know how difficult teeth are I will not fault you for it. Further, I think the shadows might be a bit dark in places, for instance her left shoulder, which adds to the toony style I think. (These points are motivation for 4.5/5)
Regardless, a cool image. I could see her being a nice counter to Black Panther or some other hero in the Marvel or DC universe. Very nice.
