A photorealistic street art mural of a massive sea turtle gliding through the flooded lobby of an abandoned airport terminal, its ancient shell covered in bioluminescent algae glowing soft teals and greens against murky water, hyperrealistic spray paint capturing weathered shell textures and barnacle details, broken control tower windows behind casting shafts of dusty amber light through darkness, mood ancient and tranquil yet eerie, composition centered with turtle swimming toward collapsed departure gates, submerged luggage carts and scattered travel documents floating on water surface adding abandoned atmosphere, color palette warm golden light filtering through broken roof contrasted with cool teal bioluminescence and airport steel grays
