A breathtaking underwater fantasy scene of an ornate grand piano suspended beneath turquoise waters, glowing with ethereal bioluminescent green light emanating from within, schools of tropical fish swimming around it, rays of golden sunlight penetrating down from the surface above creating dramatic god rays, coral formations and aquatic vegetation framing the composition, magical realism style inspired by the works of Rob Gonsalves and Vladimir Kush, volumetric lighting with subsurface scattering effects, shot with wide-angle underwater lens, vibrant color saturation emphasizing the contrast between green piano glow and blue water.
