Edición de Foto de Perfil con Gorro de Papá Noel

Using the reference photo as the base, add a classic Christmas Santa hat to the subject. - Hat details: Traditional red felt Santa hat with subtle fabric texture, fluffy white trim, and a soft white pom-pom, resting naturally on top of the head aligned with the head angle, hairline, and perspective. - Style match: Preserve the exact original art style (photorealistic, 2D illustration, 3D render, anime, or cartoon), identity, facial features, hair, colors, linework, and shading. - Integration: Match the existing scene lighting, shadows, and highlights. Add subtle contact shadows where the hat meets the hair and forehead. Keep the face, clothing, background, and all other elements unchanged. - Composition: Square avatar composition, crisp and legible as a profile picture.
