Nice work!
The snow texture on the ground looks great, and flurry of snow-fall is blurred appropriately.
The Sorceress, err...let's call her "Tits" looks good for what's being done. I can dig everything; hair looks great, clothes, her pale, almost undead skin, it's just...look at her tits. They're huge, right? Now, one would guess they would hang like that...but only if her arms were down, right? So now you have her raising her arms hiiiigh above her head, and her tits are still in a kind of "down" position....which insinuates in my head, that when she lowers her arms, those tits would sag a bit, wouldn't they?
If it were me, I'd look for a busty chick with her arms raised in an angle similar to that, and make observations...especially if she's standing. (Studying has never been so fun. :P)
What really earned the five from me, though, was the sky. That sky (and water) looks like you spent a lot of time on this...looks great!
Keep up the good work!
