Nice to see you started a mapping project yourself. The ground texture however, I assume it's a rubble texture, looks strange underneath those trees and groves. You should consider changing it to a more appropriate texture but I think you will because that project is just in the early stage of development.
Also, maps which contain Panther Turrets or other heavy Bunkers are often hard to balance, unless those objects are placed beyond the playable area.
Those ruins look great nevertheless.
I'm eager to see the "better" pictures
