Video prompt: A pair of swans glides gracefully across a serene pond, their reflections rippling gently in the water.
Defect: Deformation (any reason involved with a movement)
Explanation: The swan's body and neck exhibit a deformation resembling cotton, where the structure appears soft and inconsistently malleable. The neck stretches and compresses unnaturally, losing its rigid anatomical shape, while the body seems to fluctuate in size and texture, creating an unrealistic and distorted visual effect.
