Hi Elric,
while I can't promise an exact match to the style of the map you posted, please do feel free to take a look at my gallery anyway and see if there is anything in there that you like.

The problem with map making such as we do is that every artist has their own unique style, and the only way you could get a map that looks exactly like the one you posted would most likely be to commission the artist who made the original piece. But I could certainly try my best at getting the kind of look you like. You can reach me at rela.simila[at]gmail.com if you feel like discussing things further!
