IDENTITY PRESERVATION INSTRUCTION (CRITICAL!)
Using the uploaded photo as reference, preserve the person's exact facial features, face shape, eye color, skin tone, and unique characteristics while transforming the scene into a family portrait. The original person must remain completely recognizable with all their distinctive traits maintained.

TRANSFORMATION DESCRIPTION
Create a realistic family portrait by adding family members around the original person. The composition should show the original person positioned naturally with their family members (spouse, children, or parents as appropriate). All added family members should have cohesive appearance, matching the original person's style and era. The family members should interact naturally with the original person, showing appropriate physical proximity and emotional connection. The group should appear as a genuine family unit with harmonious visual elements.
