Futuristic military walker in a snowy pixel art storm

Create a pixel art image of a futuristic military vehicle inspired by AT-AT Walkers from Star Wars, with a bulky armored gray body supported by four sturdy mechanical legs, standing on snowy terrain. The scene is a harsh frozen environment with falling snow, strong winds, and a bluish-gray stormy sky. Use a limited 16-bit color palette with cold tones, emphasizing crisp pixels and dithering for texture. The composition should convey isolation and military power in a desolate sci-fi setting.
