Depict a grand and majestic highland cow, embodied as a mechanical being. It is constructed from intricate gears and clockwork mechanisms that are visible beneath its metallic hide. This automaton of a beast is presented in a nebula of swirling cosmic dust and starlight, combining the surreal with the wonders of the cosmos. Render the scene in a detailed concept art style, infused with a surrealist twist, as you overlay ethereal nebulae on the steampunk cow through a double exposure technique. Illuminate the scene with dramatic lighting, contrasting deep shadows and bright celestial glows, to further enhance the mystery and beauty of this surreal spectacle.
