Cylindrical Fantasy Library Tower

A richly detailed vertical fantasy anime illustration of [a young girl] sitting in the lower-left corner of a colossal circular library tower, reading an ornate dark green book. Dramatic ultra-wide fisheye perspective from floor level looking upward through the hollow cylindrical interior toward a circular open skylight revealing vivid blue sky and fluffy white clouds. The curved tower walls are packed with thousands of books, gilded shelves, ladders, balconies, framed paintings, glowing amber lamps, hanging vines, and ornate brass-and-wood architectural details. Warm golden sunlight streams down from above, blending with amber lamp glow and soft skylight. The girl has [long wavy dark brown hair], a thoughtful expression, and wears a loose white blouse with a navy blue skirt embroidered with gold stars, sitting beside glass lanterns and stacked books. A floating spiral staircase of dark wood ascends toward the right, where a sleek black cat stands on a step with its tail raised. Twenty-two colorful birds fly throughout the library and sky: 1 large blue bird cropped at the left edge, 1 yellow bird near the lower-left shelves, 2 red birds on the upper left, 1 red bird near top center, 1 blue bird near the sky center, 1 pink bird near the middle, 1 black bird near center-left, 1 glowing pale golden bird at the right, 1 blue bird on the upper right, 2 red birds on the right side, and 10 tiny silhouetted birds against the sky. Painterly fantasy aesthetic with luminous dust motes, deep perspective, rich teal-blue and warm gold color grading. No modern objects, no text labels, no borders.
