This map is actually called Gardens of Iron on BNet now.
General theme of the map is much like Metalopolis. The idea was a siege taking place in the Korhal city square where there is a Mengsk garden in the middle, surrounded by high yield mineral patches, where the most of the battles would take place. I've tried not to go overboard with the doodads just to make map playable as much as possible while still making it look pretty. There is an easy to take natural and the third, forth and high yield minerals are more exposed being in the center of the map.
