hello Lennyballa! I’ve noiced your thread… and as I’m Greek, I’ll just help you out a bit! erm… there are no palm trees in Greece, except perhaps for the ones in Crete ( island south of mainland Greece). Thus not too much sand even, unless you are planning to make it a beach thing!! :bump: You can always gear it toward the BATTLE OF CRETE - map of Greece, which would be very much in accordance with historical facts!! The Battle of Crete was a key battle in 1944 (if my memory serves me well) in which the Greek army managed to stall the German troops and thus created a diversion which was desisive for the war’s outcome (as the German troops weren’t really prepared to be defeated in Crete!
muha!
But if you want a more MAINLAND feel to your map, here’s some ideas.

that’s from a village in the north of Greece (pay attention to the pictures of the OLD Paramythia, if you wish to be closer to historical detail). Notice also that all houses have TILED roofs!!! (it’s one of the telltale signs of Greek architecture! 
Your effort is marvelous! Keep up the good work!
