Not to sure if that guy u speak with is alright...
However let's see.
First of all, work more on the detail of those hill sides, on the first picture far left the hill looks quite weird. Use the smooth feature to make the hills a bit realistic. The current state is pretty ugly, I can ensure you that it will look better with some smoothing on hill sides.
Also, I don't hope that map is made for Battle, because in that case you will have either an hour long round, or you will have a mad attackers team. Be sure the attackers actually have a chance to get up there and to win the round. Seeing the accuraty of guns, you shouldn't give the defenders to much defensives to hide behind.
It could also be a good idea to add some vegatation to the map, trees, bushes whatever make it look a bit alive. The map looks pretty boring right now.
Last, perhaps include a small building (destroyed?) or hut around the beach, so the attackers have a point were they can find cover etc. Mortars for the attacking team wouldn't be bad either.
Well goodluck!
