3D Family Peeking Through Heart Frame Prompt

Create a high-quality 3D stylized cartoon illustration based on submitted references of family members, all peeking out from behind a matte heart-shaped opening. Only their heads, hands (where applicable), and upper torsos should be visible, looking playful and hiding.
Subjects must be arranged in descending age order.
The composition should feature a soft, textured beige. The entire outer background is a beige gradient; the heart-shaped opening borders are the same colour but slightly darker; the inner background is a dark violet gradient, creating a contrast that highlights the brightness of the characters. The style must have a soft Pixar/Disney animation look, with large expressive eyes, smooth skin, and slightly enlarged head proportions for cinematic charm, while retaining the recognizable facial features, hairstyles, and age from the reference photos.
Everyone is gently holding the edges with small hands/paws and leaning slightly forward with curious, playful expressions. The lighting should be soft studio light with warm, gentle highlights and no harsh shadows.
The image must be a 1:1 aspect ratio portrait with centralized framing and shallow depth of field. The final render should be ultra-sharp 4K, in an Octane/Unreal/Disney rendering style.
