Tips for Better Images

1. Be descriptive: "Woman in office" → "Confident woman in her 40s, silver blazer, modern glass-walled office, warm afternoon light"

2. Specify style: "photorealistic", "digital illustration", "watercolor", "anime"

3. Describe lighting: "Soft natural light", "dramatic side lighting", "golden hour glow"

4. For character consistency: Describe the character in detail first, then reference "the same character" in subsequent prompts.

5. Include composition: "Rule of thirds", "close-up portrait", "wide establishing shot"
