This is my final choice. The lighting and overall tone of this photo appears soft and gentle, the blue tones of the sea are consistent and harmonious, giving the whole photo feelings of tranquility and calmness; the natural texture of the fabric and the folds and curves created also enhances the sense of peace and serenity; and the black and white beach add contrast without disrupting the overall color scheme; the elements are effectively balanced-interacting with each other to create a mysterious and engaging underwater scene-the fish figure is clearly the focus point, and the background provides context and depth without being distracting at the same time.
