Great! If I may suggest something : I think the snow is "too white". It would probably benefit some darker areas. I know snow is supposed to be white, but I feel like such a contrast catches the attention a little too much. The hair of the character on the other hand is hard to see because it's so dark. Maybe a light outline would help? Like what's explained in this tutorial : https://youtu.be/XVo5IcY9Mbo
But again, I think this is really good work :)
