A breathtaking futuristic underwater metropolis enclosed in massive glass domes, illuminated from within by city lights glowing against the deep blue oceanic backdrop. Flying cars glide through water between transparent bubble structures housing buildings and streets. Sunbeams pierce through the semi-dark ocean surface, creating dramatic light rays. Vibrant coral formations and aquatic plants grow along the dome exteriors, adding organic beauty to the architectural marvel. In the distant background, the silhouette of a colossal whale appears, emphasizing the scale and wonder of this subaquatic human settlement.
