How to preserve facial likeness in an AI greeting card
Likeness combines face shape, feature spacing, age, expression, hair, and posture rather than one magic setting.

Use a few useful angles
A front view supports proportions, a slight profile helps the jaw and nose, and a smiling image supports expression.
Separate style from anatomy
Clothing, light, background, and genre may change while eye shape, face outline, age, and smile stay fixed.
Do not beautify automatically
Heavy smoothing and a changed face outline can reduce recognition.
Compare at the same scale
Place source and preview side by side with similar face size.
Request precise revisions
Point to narrower eyes, wider smile, or the original hairline instead of simply asking for “more likeness.”
