Exobrick has always been adept at taking several official and custom parts and creating something with real appeal. His latest creation is no exception.
The hat is from Si-Dan, the body wear is from BrickTW, and the gas mask and shield are from Amazing Armory. The Auto-9 hand cannon is courtesy of BrickArms, while the cape and sheath are from MMCB.
The head? It's from the new LEGO Star Wars Embo minifig. I can see the head for this and the Imperial Pilot showing up in a lot of custom creations this year.
