Pro Tips for Perfect Demon Hunter Photos
- Never delete the face-reference line. It’s what keeps the idol you instead of a random K-pop trainee.
- Pick your side deliberately. Huntr/x prompts use violet-gold tones; Saja Boys use turquoise-gold. Mixing them muddies the look.
- Name the songs. Adding “Golden” or “Soda Pop” performance context pushes the AI toward the right stage aesthetic.
- Gemini first for faces. Google’s Nano Banana model holds your identity best through heavy stylization.
- Regenerate for the glow. Eyes and demon marks vary per generation — keep the one where the effect looks cleanest.
