Good start, though I'd prefer if there was a better border than just a giant baseplate cubes, and if I remember from Discover Channel the beaches were a lot larger.
I’m planning a scale map of Omaha beach, which was 300 yrds long to the sea wall, then another 200 yrds to the cliff wall. Also, adding features that would be in the real thing such as: lots of mines, artillery, obstacles, and heavy machine gun fire (if i host, spawn killing the 1st/29th divisions is allowed).
