Edit the skull robot tank to have 4 distinct arms, each hand holding a different weapon: a large industrial blade, a blaster, a menacing syringe, and a claw. The exterior metal should be extra shiny silver grey, with inside cables and tech almost black. Smoke from the top is dark shaded. The skull face is dropped down low and out in front, matching the reference. The whole subject should be compact and not tall, in a clean outline retro stickers style with transparent background.emoji
