Try removing the bright white contours on the snow (especially around the door). They give the image a very pixelated look when not antialiased against the dark color of the wall.
Also, I think the problem with the snow by the door is that the snow drift is concave rather than convex. Actually it looks like it's flat against the wall at the top.
Otherwise it's a great image!
