XD Drop shadows have always been my way of making the icon seem like it's continueing but really it's not.
However, as to my solution to the bottom corner. I would have added a small amount of red [color copied from the original icon] and placed it on screen about 50% [just so it's barely noticeable in the background. On top of that layer I would have croped that part of the roof under the tiny text next to sesshoumaru [sp?] and horizontally flipped it. Then I would use a blurred circle eraser in order to erase around the edges so it would match. For the top of the roof.... I would crop the area above the tiny text and flip it until it matches the direction of the roof. [of course this layer is under the tiny text]. Then I would blur the edges again with the eraser. ;D
