Scultura fotorealistica di sirena di sabbia su una spiaggia soleggiata

Create a photorealistic digital art image of an intricately detailed, full-body sand sculpture of a mermaid on a sunny beach. The sculpture is made entirely of sand, holds a staff, and is depicted with ultra-precious details. The background features a magical, volumetric lighting effect with a summer landscape. The image should be in 8K resolution, with sharp focus, studio-quality lighting, and lifelike textures. Style references: trending on Artstation, by CGSociety, photography-inspired digital art.
