masterpiece, hyperrealistic digital painting, dark and dramatic. Dynamic three-quarter portrait of a lone astronaut in a vintage spacesuit, submerged in deep ocean water. Close-up intimate cam shot. Their body is gently turned, reacting to a swirling water current. Powerful light beam from their helmet cuts through the murky water, illuminating floating algae and dust particles. Swirling bioluminescent plankton create a vortex of light around them. Intense particle effects, water distortion, strong rim lighting.
