It looks nice, and I'll give you a bit of rep as well for being willing to contribute from the start - Thanks, and welcome to the Guild!

Does the really-dark coloration-blotchiness have a meaning? It dulls down the map - if there were other details they'd be obscured. The photorealistic terrain clashes with the strong linen background texture - one says 'computer' and the other says 'hand-done'. The mountains are nicely done, though.

It's a great start to a mapping mania - I hope you're well and truly hooked :-).
