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. Add dark shaded smoke from the top. The skull face is smaller, dropped way down and put forward in front of the tank body. The whole subject should be compact and not tall, in a clean outline retro stickers style with transparent background.emoji
