Generate an artwork that misses the mark in portraying an ultra-modern, futuristic atmosphere. The flying saucer-like UFO should lack visual interest and fail to convey advanced technology. The mansion's design should lack creativity and fail to incorporate futuristic elements. Use a dull and monotonous color palette and avoid sharp geometric shapes, resulting in a lackluster composition. Overall, create an artwork that lacks the excitement and intrigue of a futuristic scene.
