ミオさん誕生日おめでとう🎉

A medium shot, eye-level illustration of PixAI_Mio centered in a dreamy birthday celebration. PixAI_Mio, a cat girl with multi-color gradient white and pink hair, a heart-shaped cowlick, purple eyes, an eyepatch, and cat ears and tail with a ribbon, beams with a cheerful smile and cute expression; she stands behind a table, her hands gently resting on its surface. She wears an elaborate military-style idol dress consisting of a blue jacket with epaulets, a high collar, gold trim, a red bow tie with a brooch, a sash, and a layered lace-trimmed skirt with frills. In the center, large decorative text reads "Happy 4th Birthday MIO", surrounded by floating colorful metallic confetti and heart-shaped metallic balloons. On the table sits a birthday cake with pastel pink cream roses, gold stars, and a number 4 topper, beside a ribboned gift box with flowers. The scene is rendered in an anime style with strong line art softened by watercolor washes, featuring shimmering particles of light, a soft haze, and a pastel fantasy palette with strong atmospheric perspective.
