> Use the original uploaded photo. Keep the couple exactly as they are, without changing anything about their faces, bodies, colors, or lighting. Add the Colossal Titan from the anime Attack on Titan, appearing partially behind the concrete dam, positioned to the right side of the image (not centered), as if peeking from behind the wall. The Titan should look realistic and intimidating, scaled much larger than the humans. Maintain the original sky, natural lighting, and vegetation in the background. Do not modify the couple or any part of the original foreground, only add the Titan in the background.
