Cygnar Hunter Light Warjack from Privateer Press's "Warmachine' wargame.

According to the game, they are designed to be all terrain warjack (steam powered mecha) killers. The Long Arm Cannon (mounted on the left) fires alchemically hardened penetrator rounds that punch straight through most armor plating. The axe is nothing spectacular, but it allows it to hack its way through dense vegetation.

Im not quite as happy with the silver. Just too muc of it I think. Not going to paint over it though. It also needs a second coat of paint as its still kinda looking nasty.
Anyway, I hate blue, so no standard Cygnar colors. Tan is much nicer.
