There might be some missunderstanding here. We are looking for some "artist" style map makers, not ingame maps, rather something similar quality as this:
THIS or
THIS.
We are looking for a global map, showing all the zones that are fully or partiall customized and how they are connected. If it could match to our design theme, thats a plus.
So basically check out the listed referencies, and you will know what we are looking for.
Thanks!
