I agree. Take out the top row of the roof snow (one row will work).
Do something about the pillars right outside the door, and if you're using the whirlpools as portals, consider using only one on each side instead of many.
In addition to the large pillars in the foreground, the small mountains were included in spots to enhance the panorama for this particular map. (32-bit style). Those whirlpools could be time portals. Well, thanks for the advice..
