Character replacement workflow for the Strawberry Latte doll box
About this document
This is the step-by-step guide for swapping the figure inside the Huda Beauty Strawberry Latte doll box with a user's photo using AI. The box, branding, and all product visuals stay completely untouched — only the person changes.
Before You Start
Run through these three checks before opening the platform. Skipping them is the main cause of wasted generation runs.
  1. Lighting — Reference photo must be softly and evenly lit. No harsh shadows or flash.
  1. Source asset — Use the master file at 2048px minimum. No screenshots or compressed exports.
  1. Reference photo — In focus, unfiltered, full face visible, neutral background, preferably white.

Platform Selection This workflow will only work with Nana Banana Pro Model
The Process
Six steps, in order. Do not skip or reorder.

PROMPT
Preserve Image 1 [doll box] exactly as it appears in every detail except the figure inside the box. Replace only the figure with the person from Image 2 [reference model], keeping their exact likeness, skin tone, and bone structure. They are a real human model with realistic skin, not a doll. Retain any natural skin texture visible in Image 2 [reference model], no overpolishing. They recline in the same pose: lying on their side toward camera left, legs extended, upper body propped on one arm, confident expression facing camera. Outfit is a deep red or burgundy look that mirrors the energy and styling of the original figure but adapted naturally to the subject: draped, fitted, or textured depending on what suits their presentation, always within the same deep red colour world. Makeup and grooming are polished and appropriate to the individual. Hair is styled naturally to match their texture, length, and style as seen in Image 2 [reference model]. Realistic skin, shadow-free for maximum makeup visibility. All box elements remain untouched: structure, text, typography, Strawberry Latte branding, hudabeauty wordmark, accessories, background, colour palette, and graphics. Photorealistic. Use the person in Image 2 exact face, including microtextures and skin details. Skin finish and makeup texture are clearly visible, with natural skin quality appropriate to age. high end campaign. Fine skin pores are present across the face, soft peach fuzz is visible along the cheeks and jawline, and individual lashes are clearly separated rather than clumped. Minor imperfections remain visible, preserving a lived-in, subtle skin sheen on forehead, human surface rather than a smoothed or artificial appearance.

Check every output against these six points before sharing anything with the client.

The face must clearly match the reference photo. Proportions, skin tone, and features intact.
