"Avoid soft, blended textures or smooth, plastic-like surfaces. Do not include any unrealistic or polished finishes that deviate from the rough, grainy texture of sand. Exclude shiny or metallic materials, and avoid overly saturated colors. No abstract or cartoonish forms—focus on realistic, detailed sculpting. Do not add elements like water, glass, or other reflective surfaces, and avoid any blurred or faded edges. Ensure there are no extra elements like overly dynamic motion effects or futuristic sci-fi elements."
