A photorealistic billboard set against a lush, rolling hillside, reminiscent of the iconic Hollywood sign, featuring the text “PromptHero” in large, bright letters. The letters are designed with a sleek, modern twist, each one cast in a shimmering silver that reflects the golden hues of a setting sun, adding a magical glow. Dotted around the hillside are blooming wildflowers in vibrant colors, and a few scattered pine trees swaying gently in the breeze, adding to the scenic beauty. The sky is a brilliant blue with wisps of clouds, creating the perfect backdrop for this majestic display.
