3D Animated Family Portrait in Heart Frame

Create a high-quality 3D stylized cartoon illustration based on the submitted reference photos of family members, all playfully peeking out from behind a large heart-shaped frame. Only their heads, hands, and upper torsos should be visible. Members must be arranged in descending age order on the upper left and upper right, with the youngest family member centered slightly lower in the foreground, creating a balanced family composition. The entire outer background is a very dark black; the heart-shaped opening borders are the red-orange gradient; the inner background is a rich dark-red to warm-red gradient, creating a contrast that highlights the brightness of the characters. Use a soft, polished 3D animated-film look with large expressive eyes, smooth skin, softly exaggerated facial proportions, and slightly enlarged heads, while preserving the recognizable facial features, hairstyles, age, and overall appearance from each reference photo. Each family member should gently hold the edges of the heart frame with their hands and lean slightly forward with cheerful, playful expressions. Use soft studio lighting with warm highlights, subtle facial glow, and no harsh shadows. Create a 1:1 square composition with centralized framing, polished depth and dimensionality, crisp facial details, and an ultra-sharp 4K-quality 3D render with premium cinematic animation rendering.
