Prompt
Use the uploaded family photo as the reference for every person. Preserve each person's recognisable facial features, natural skin tone and relative size as closely as the model permits. Check every person against the reference before sharing.

Place the family in a cosy living room on Christmas Eve, gathered beside a tall decorated tree with warm white fairy lights. A fireplace glows softly to one side.
Arrangement: sitting together on a sofa, kids on the floor in front.
Clothing: matching knitted sweaters in deep red and cream.
Lighting: warm tree lights and firelight on faces, soft window light from snow outside.
Style: natural photograph, 35mm lens, gentle bokeh on the lights.
Format: landscape 3:2.

Avoid: extra people, merged hands, distorted children, text, changing anyone's face.

Customise

For example: sitting together on a sofa, kids on the floor in front.
