油絵風 誕生日 ポートレート

Transform this family birthday photograph into an elegant, hand-painted oil portrait with vintage color grading. Use warm ivory, antique gold, muted olive, and soft sepia tones. Add delicate painterly brushstrokes, subtle canvas texture, gentle lighting, and refined shadows. Preserve the exact faces, natural expressions, dog, birthday hats, and cake. Create a nostalgic, sophisticated heirloom painting while maintaining the original composition and intimate atmosphere.
