Valley Between Sand Dunes on a Tropical Beach

Photorealistic valley on a tropical beach: a narrow emerald-green valley carved between wind-swept sand dunes and towering limestone cliffs; a clear stream winds through lush grass and tropical flowers toward a turquoise sea. Palm trees line the banks, golden-hour sunlight casts long shadows, soft waves lap on pale sand, and a few seabirds circle in a bright blue sky.
