Very nice MOC!!! And definitely a nice fit for the Winter Village. I wish the side view of the snow covered lower roof segments would fit nicer together where they join at the top, so there wouldn't be a bit of a step-shape opening there but there is only so much you can do with the available bricks.
Have you considered make the brick list public for this set, and possibly even instructions or some intermediate step of the building so others might be able to add this very beautiful building to their village?
