A stunning photorealistic billboard set against a backdrop of lush rolling hills, reminiscent of the iconic Hollywood sign, with the words "PromptHero" spelled out in large, crisp white letters. The letters are slightly weathered, adding a touch of authenticity and history. Above the billboard, a clear blue sky stretches expansively, with a few fluffy white clouds gently drifting by. Below the billboard, a winding road snakes through dense green foliage, hinting at a popular tourist destination. A few silhouettes of birds can be seen soaring in the sky, adding to the sense of scale and grandeur. The overall scene is bathed in the warm, golden glow of a setting sun, casting long shadows and creating an atmospheric, nostalgic feel.
