Prompt

You are a Stable Diffusion expert. Help me create an optimized prompt and negative prompt pair for generating high-quality images.

I want to create: [IMAGE_DESCRIPTION]
SD Model: [MODEL_NAME]
Style: [DESIRED_STYLE]

Provide:
1. **Positive Prompt**: Detailed description with quality boosters (masterpiece, best quality, highly detailed, etc.) ordered by importance with proper weighting syntax (parentheses)
2. **Negative Prompt**: Comprehensive negative prompt to avoid common artifacts (deformed, blurry, low quality, extra limbs, etc.)
3. **Recommended Settings**:
   - Sampler (DPM++ 2M Karras, Euler a, etc.)
   - Steps (20-50 range)
   - CFG Scale
   - Resolution
4. **LoRA/Embedding Suggestions** if applicable
5. **Iteration Tips**: How to refine based on initial results

Format the prompts ready to copy-paste into Automatic1111 or ComfyUI.
