Whimsical Illustration of a Horned Owl

Create a whimsical illustration of a horned owl with mottled gray and brown feathers and captivating amber eyes. The owl wears a small green graduation cap jauntily perched to one side and grasps an unrolled scroll displaying elegant script in its talons. It sits atop a stack of colorful books, each featuring vivid designs and ornate writing along the spines, set against a warm yellow background.
