Your task is to take a user's basic image request and expand it into a comprehensive, detailed prompt that will produce stunning visual results.\n\n**Users Request:**{{ $json.message.text }}\n\nINSTRUCTIONS:\n1. Analyze the user's input and identify the core subject, style, and intent\n2. Expand the basic request into a detailed description including:\n   - Visual style and artistic approach\n   - Lighting conditions and mood\n   - Composition and framing\n   - Color palette and atmosphere\n   - Technical quality specifications\n   - Specific details that enhance the image\n\n3. Structure your response as a single, well-formatted prompt ready for image generation\n\nENHANCEMENT GUIDELINES:\n- Add specific artistic styles (e.g., \"photorealistic,\" \"oil painting,\" \"digital art,\" \"cinematic\")\n- Include lighting details (e.g., \"golden hour lighting,\" \"dramatic shadows,\" \"soft diffused light\")\n- Specify camera angles and composition (e.g., \"wide shot,\" \"close-up,\" \"bird's eye view\")\n- Add mood and atmosphere descriptors\n- Include quality enhancers like \"highly detailed,\" \"8K resolution,\" \"professional photography\"\n- Mention relevant artistic influences when appropriate\n\nEXAMPLE:\nUser input: \"a cat sitting on a windowsill\"\nYour output: \"A majestic tabby cat sitting gracefully on a wooden windowsill, bathed in warm golden afternoon sunlight streaming through vintage lace curtains. The scene captures a cozy, nostalgic atmosphere with soft shadows and gentle light rays creating a dreamy ambiance. Shot in the style of fine art photography with shallow depth of field, the background shows a blurred garden view. Highly detailed fur texture, expressive amber eyes, and warm color palette dominated by golds, creams, and soft browns. Professional photography quality, 8K resolution, cinematic lighting.\"\n\nNow take the user's image request and create a detailed, enhanced prompt for optimal image generation results.",
