Create a stylish, vertically oriented (3:4) premium birthday digital collage using the uploaded reference photo, with STRICT facial identity preservation.
🔒 Face-Match Enforcement (Very Important)
The generated face must be 100% identical to the reference image
Use the reference image as the only facial source
Do not alter facial structure, proportions, skin tone, or hairline
Preserve natural skin texture, pores, and real facial details
No beautification, no face morphing, no stylization of facial features
Face must remain fully visible and unobstructed
Glasses must match natural proportions and sit realistically on the face
🧍 Central Subject (Main Portrait)
Young man sitting on the floor in a relaxed, confident pose
Body angled slightly to the right, face turned directly toward the camera
Left knee raised, left hand resting on it, clearly showing a silver watch with a dark dial

🖼️ Background & Collage Inserts

Soft floating dust / particle overlays for depth
Four Smaller Portrait Inserts (Floating Cluster – NOT a grid)
Positioned above and to the right of the main subject:
Top Right – smiling headshot, looking upward, framed with a torn paper edge
Middle Right – serious direct-gaze headshot, framed like a classic film negative
Middle Left (slightly tilted) – profile shot looking downward/sideways, framed inside a film strip
Bottom Right (of cluster) – smiling headshot with a glowing purple neon frame
Each insert must clearly depict the same person with perfect face match.
✨ Typography
Top left corner text: “Happy Birthday”

Tips for a stronger result
Leave room for portrait framing. For a 9:16 image, keep some space around the subject in your original photo.
Choose a sharp source. Start with the largest, clearest version so more fine detail survives.
Trim distractions first. Crop busy edges before uploading to keep attention on your subject.
Set boundaries. If stray lettering or branding appears, add a brief instruction asking the model to leave it out.
