Generate a high-quality image of a mecha with a gun, Skyfire, in a sarcastic pose, with a focus on vibrant colors and realistic textures. The image should be in the style of Disneypunk and have a hyper-realistic quality, with flat grey and red-yellow colors. Incorporate elements of a trench crusade and ensure the image is exploitable and beautiful. The mecha should have an official details photo and be restored to its original color. Please provide the image in a coherent and symmetrical composition, with the other mecha in the background used for flight. Output should be in Unreal Engine or Octane Render style.
