Doesnt the white mountains look much better than the brown colour. I thought so.

I think it's an interesting idea and it does have a small appeal, mostly because it is so different, but I don't think it looks better.
There is so much blue already, with the the white/light blue mountains etc. I think it over powers the other colours on the game too much.
I do like the alternate big foot to match the mountains though, very clever.
