Create a cute chibi anime sticker illustration of a sleepy angel girl floating against a flat bright sky blue background. The character has pale skin, half-lidded teal eyes, a tiny neutral mouth, and long pale blonde twin tails with blunt bangs and face-framing locks, tied with exactly 2 large black ribbon bows. Above her head is 1 thick golden dripping halo, with exactly 3 small golden sparkle stars around it. She has exactly 2 small white feathered angel wings behind her. Dress her in an oversized teal green zip-up track jacket with a high collar, silver zipper, and two white stripes down the sleeves, paired with a short black pleated skirt. Pose her seated and floating in midair with one knee raised and the other leg dangling, slightly slouched with a bored, sleepy expression. She wears white knee socks with black horizontal stripes near the top and white sneakers with yellow laces. Use a clean kawaii digital art style with thick black outlines, rounded simplified shapes, soft flat colors, minimal shading, no text, centered composition, full body visible, playful mascot-like proportions.
