When the face is turned partly away in a busy scene, the output still feels like the same character but cannot be fully verified.

What was measured

Identity preservation

How closely the generated face matches the reference image across scenes.

decisive for this rankingtransformation

This is the core of the task: the tool must keep the same character looking like the reference image across scenes. (3 of 3 judges)

What was given, what came back

Test input: Three-quarter face portrait · image

Input — what we sent

Input file 1 — as supplied

Three-quarter face portrait — Input file 2 — as supplied

Three-quarter face reference image with medium-dark skin, tight curly hair in an updo, bindi, and a floral dress. The partial angle and softer lighting make it a harder reference than the frontal portrait and are meant to stress identity consistency.

Why this input is hard

· Identity preservation with partial face angle
· Hair texture and updo retention
· Skin tone fidelity
· Reference-image difficulty under softer lighting

Output — unretouched

Also checked on this input — same tool, 5 other criteria

Accessory & detail retention⚠ StruggledDense natural curls are not retained; the tool flattens them into straight, oily-looking hair.Accessory & detail retention✓ WorkedIt preserves curl volume and hair texture better in the market scene than it does in the interrogation scene.Expression accuracy✗ FailedThe same neutral-expression failure repeats on a second reference, so the tool still misses the prompt's angry, guarded tone.Scene compliance✓ WorkedIt can stage a lively crowded market with a natural walking pose, sari styling and believable bag placement.Scene compliance◐ MixedIt reproduces the formal outfit and room, but the lighting becomes too bright and clean for an interrogation scene.

measured on Identity preservation

ChatGPT✓ WorkedPreserves face shape and structure well in a frontal composition, though the report notes a slight darkening and a marginally wider, rounder face than the reference.Gemini✓ WorkedWith a 3/4 reference, the interrogation-room output still preserves identity well, keeping face shape, skin tone, curly hair texture, eyebrows, and overall structure close to the input.ImagineArt✓ WorkedThe interrogation-room output stays close to the reference in face shape, skin tone, expression, posture, and overall appearance.Scenario⚠ StruggledIdentity drifts in a crowded full-body scene, with a narrower jawline and a thinner body making the result read as a similar-looking person rather than the same subject.
