부정적 프롬프트:
A large, reinforced concrete backwash gate for a reservoir at a shrimp farm near the beach. The gate structure is sturdy and industrial, with thick concrete walls and a smooth sliding metal panel at the front. Surrounding the gate, there is beach sand with scattered grass patches, and the reservoir water is visible in the background, calm and reflecting the clear sky above. In the distance, a few mangrove trees line the horizon, adding a natural touch to the coastal setting. The scene is captured on a sunny day with soft shadows, enhancing the industrial yet natural environment.
