I want to help build the map, but my pc (the one decent enough to run MC) is having some problems, and is being fixed. I'm not sure when I'll get it back.
About the skins, I'll pm you my current skin later, I'd like a Christmas hat on it. :]
Oasis, perhaps? Unless you're looking for something else, either way, just type "best 1.4.7 minecraft adventure maps" into Google like I do :P. Best of luck.
