Essential Elements

• Detailed Descriptions – Highlight unique features and dynamic actions.
• Rich Environment – Specify lighting, background, and context.
• Style or Artistic Reference – Mention art movements, camera angles, or visual aesthetics.

Advanced Techniques

• Weighting – Use parentheses to emphasize key components.
• Negation – Add --no to exclude unwanted elements.
• Style Fusion – Combine multiple styles (e.g., "watercolor + cyberpunk").
• Reference Images – Provide visual cues to guide the AI.
