I must say that I love the work as a whole, but feel that there is an issue with the perspective/shape of the head and face. I look forward to seeing such tremendous skill develop.
It seems to me that you are experimenting on this one. Looks more "impressional" than your other works.
J'aurai, personnellement mi un légé flou directionnel sur la neige mais sinon j'aime bien les effet de flou sur le personnage.
