"Create an ultra-realistic 3D model of a plush teddy bear in T-pose, holding a glossy red heart. Soft, fluffy light-brown fur with detailed fibers. Large, round black eyes, a small dark brown nose, and a gentle stitched smile. The red heart is smooth, slightly reflective, and has subtle curvature. Ensure intricate fur texture, lifelike stitching, and high-resolution surface details for perfect AI recognition and 4k realism .", #valentine#,
