maxsdaddy - Well the only place where the key would fit in was on the left side ofthe map, so I had to hide some details of the map. But if you're interested I can put up a version of the map without a key.
Schwarzkreuz - The texture overlaying the water and farmland are created by using the pixelbender addon for photoshop. I've actually done a tutorial on it here on the guild. It describes the method I'm using but lately I've started to decrease the effect a bit. You have to play around with it and see how it works. You can also see a tutorial over on my blog. It describes the same process in different words.
