Create an image of a hand holding a small, brightly colored fish with a more elongated body shape and a smooth texture. The fish should have a vibrant blue and yellow pattern instead of green and orange, and the background should feature a calm lake surrounded by lush, green grass and trees instead of any identifiable landmarks. The hand should appear slightly larger in proportion to the fish, emphasizing its catch. Ensure there are no brand logos or identifiable objects in the scene.
