Create an image that depicts Ariel, a young mortal man, and Lucas, a translucent water spirit resembling the waves, in a loving embrace in the beautiful underwater world they inhabit, with vibrant corals and colorful fish, symbolizing their magical encounter. The image should have predominant shades of blue and green, conveying a sense of romance and underwater mystery. Ensure that the image is photorealistic, as if it had been captured with a professional camera, and it should be a half-length portrait. Please avoid any errors such as incorrect hand placement, extra limbs, missing facial features, low-quality underwater depictions, poorly drawn character anatomy, missing limbs or fingers, scary atmospheres, ugly character representation, out-of-frame compositions, extra limbs or masks on characters, mutilated appearances, paintings on faces, deformed character representations, extra fingers, mutated hands, poor hands or facial drawings, or fantasy-style mutations in characters.
