Tweaking Prompts for Custom Results
While the 25 prompts above are detailed and ready to use, every user has unique creative goals. That’s why it’s important to tweak prompts according to your requirements. Small adjustments can help you personalize the outcome while still keeping the face identical.
Here are some common tweaks you can make:
Change Colors – Modify outfit, armor, or lighting colors to match your preference.
Background Swap – Replace settings like “castle wall” with “mountain peak” or “futuristic skyline.”
Add Props – Include objects such as books, swords, flowers, or instruments.
Style Adjustment – Switch between realistic, cartoon, anime, oil painting, or cinematic styles.
Lighting Effects – Specify dramatic shadows, golden-hour sunlight, neon glow, or soft candlelight.
Example of a Tweaked Prompt
Original Prompt (Portrait):
“Transform the uploaded image into a royal-style portrait with jeweled crown and velvet robe, seated on a golden throne with a grand palace hall in the background. Keep the face identical.”
Tweaked Version (User Request – add darker mood & candlelight):
“Transform the uploaded image into a royal-style portrait with jeweled crown and velvet robe, seated on a golden throne in a dimly lit medieval hall, illuminated only by flickering candlelight and stained-glass reflections. Keep the face identical.”
See the difference? A simple change of background and lighting completely changes the mood of the final image.
Why Add “Keep the Face Identical”?
One frustration with AI image generation is that it often alters facial features. Adding the phrase “Keep the face identical” ensures that the edited image remains true to the original, while still allowing for stylistic creativity in clothing, setting, and overall theme.
