The three circles on the front are the Fusion Cannons, the hump towards the back by the top phaser is suppose to be the bridge. The purple box on the back is the warp engine. Just trying to make it look differant, as the mini shows most of the detail is on the bottom of the ship.
Also the hull colour is according to the ADB web site is blue/grey which is what I tried to get. Yes I know the texture look plain but im just starting on them.
