Hello there! Made another one of these, mostly due to my abundance of alien fodder

Used the Diablo figure as the base, (again), arms and legs from dog alien. Head/neck from dog alien, heavily modified/resculpted. Hands and tail from Covenant alien. Feet from hasbro's resurrection warrior, with joints sculpted on. Sculpt applied throughout the figure to make the various parts blend together. The secondary arms are also from the covenant alien, though they were added at the end. I noticed, when I was taking apart the diablo, that the joint sockets on the back were almost exactly the same size as the covenant alien's joints. A bit of dremeling made them fit properly.

As for the color, I used the coloration of the Boiler alien, from the game Aliens Colonial Marines, as reference. Which is a sort of yellowish, dried out bone color with neon green detailing.
