A hyper-realistic, ultra-detailed autumn scene featuring an adorable baby sitting on a bed of colorful fallen leaves under a large tree. The baby is dressed in a cozy, fluffy brown teddy bear onesie with cute round ears on the hood, adding to the warmth and charm of the scene. The baby also wears a snug white knitted beanie with a small black tag that has text, slightly tilted to the side. The baby's expression is joyful, with bright eyes and a soft, mischievous smile. The baby’s chubby cheeks are slightly rosy, reflecting the crisp fall weather. The background features golden yellow, burnt orange, and deep red autumn leaves, along with green foliage sprouting around the base of the tree. Soft natural daylight filters through the leaves, casting a warm, golden glow over the scene. The depth of field is shallow, keeping the baby as the primary focus while slightly blurring the background to create a dreamy, cinematic effect. The atmosphere is cozy, inviting, and heartwarming, capturing the essence of a perfect autumn day.
