Transform the scene to be fully underwater. The woman is now floating weightlessly, posing gracefully in crystal-clear, vibrant turquoise ocean water. Her long blonde hair should be drifting elegantly and fanning out with the water's current. Illuminate the scene with realistic sun rays filtering down from the surface, creating beautiful, dappled caustic light patterns that play across her and the water. A few tiny, realistic air bubbles should be floating gently past her.
