Well, it's one of the better that I've seen from your class. The art was decent but seemed a bit rushed (I love the fire) But as always I'll list a few changes that should help.
1-Rolling mountains, I don't mind the peaks but there's just too many sharp angles, the background would look much better if the mountains had a bit more character.
2-The sounds of the wild are a bit too loud compared to whats happening up front (I don't mind louder wind that looks like a generally windy place)
3-Animation lineup, though the artwork is decent, I've noticed a few things such as sounds not lining up with animation such as the fire and sharpening the sword, as well as that the fire is not in the center of the melted snow, and as for how loud the wind is shouldent that cloud be moving faster?
