I like most the test900_11 map from gandalf, as the land goes around a sea in the middle, with a bridge in the midle.
Then the Trophy4 is also nice, but i would connect the seas together in a ring and make a bridge at the bottom of the map, so that there are nice possibilites for multfront wars.
The other maps are more ore less big parts of land and water around them.
and btw. thumbnails would be a good thing, as watching 30MB pictures load is not very entertaining
