It looks wonderful. The idea and the modeling are suberb, and the way her hair frames her face… beautiful. There are some minor problems with her face, her pose, and some of the textures/particles.
As some others, I think her nose is a bit too long. Her eyes also seem a bit bigger than I think they’d be, but they’re shadowed so it doesn’t look bad.
Both hands could be positioned a bit better. I suggest looking at a mirror and making a taking a similar pose and taking notes.
I think her skin is a bit too perfect. It’s like jello, or porcelain, or something like that - no wrinkles, no spots, nothing. The metal parts could be less reflective and have a more cloudy surface. They look almost like small mirrors now. The fur particles could also be a bit more random, especially in the rim of the hood. You might also want to experiment with a barely visible cloud of breath.
Very, very good, and much better than I can do. Good luck in becoming even better!
