Portrait sous-marin d'une chasseuse sous-marine athlétique

A photorealistic underwater portrait of an athletic young woman swimming forward in a deep blue ocean, captured in a dynamic 3/4 frontal angle. She wears a fitted navy short-sleeve dive suit, tactical harness and belt, fingerless gloves, and black freediving fins. In her hands she holds a sleek speargun with a visible metal spear tip. Her long dark hair flows freely around her face, soft light rays and volumetric shafts from the surface illuminate suspended bubbles and particles, creating caustic highlights on her skin. Expression is focused and determined, skin tones natural, subtle makeup, high detail on facial features and gear. Composition centered, slight motion blur on fins, crisp focus on eyes and speargun, cinematic color grading with cool teal and deep blue contrast, high dynamic range, sharp textures, realistic water refraction and surface reflections, dramatic yet serene atmosphere.
