Be Descriptive

CopyBad:  "cat, sunset"
Good: "A fluffy orange tabby cat sitting on a wooden fence,
       watching a vibrant sunset over rolling hills.
       Warm golden and pink light illuminates the scene.
       Photorealistic style with soft focus background."

Specify Visual Elements

• Lighting: "soft morning light", "dramatic side lighting", "golden hour"
• Style: "oil painting", "watercolor", "3D render", "photorealistic"
• Mood: "serene", "dramatic", "whimsical", "mysterious"
• Composition: "close-up portrait", "wide landscape", "bird's eye view"
• Camera: "35mm lens", "shallow depth of field", "wide angle"

For Style Transfer

When using reference images, be explicit about what to transfer:

• "Match the color palette and brushstroke style of the reference"
• "Keep the artistic mood and lighting from the reference image"
