LEGO mecha-building master Moko has done it again with his AM-01 alien mecha. The build features seamless integration of System pieces with parts from the Stormtrooper constraction figure to give the build curves and shapes not possible with normal bricks.
Although I wasn’t sure of the choice at first glance, I like the pearl brown accents under the arms, as it makes for a more original color combination. And yes, it does appear to have some sort of cannon for a belly button.
