Aqua-Haired Anime Street Portrait

Create a vibrant vertical anime illustration of {argument name="character name" default="Mahilo"}, a stylish teenage girl standing in profile on a bright Japanese shopping street, viewed from mid-thigh up with a dynamic low-angle fashion-photo composition. She has extremely long flowing {argument name="hair color" default="turquoise aqua"} hair streaming dramatically to the left in the wind, with glossy highlights, loose strands, and a few ahoge flyaways; She wears an oversized shiny white track jacket with two bold cyan stripes running down each sleeve, ribbed cuffs and hem, a slightly wrinkled glossy fabric texture, and a high collar; pair it with tight black shiny short shorts. Add a black backpack with thin straps over both shoulders, visible side pockets, zipper pulls, and one yellow chick-shaped charm keychain hanging on the back. Pose her with one hand tucked into the jacket pocket, hips angled, torso turned slightly away from the viewer, conveying casual confidence. The background is a sunlit narrow urban street in Japan with tall buildings on both sides, strong perspective lines, blue sky glow, overhead wires, storefront signs, and shallow depth of field; include exactly six visible street-sign elements: one large red sign on the left, one blue vertical sign with the number 2 on the upper right, one red circular upward-chevron sign, one blue circular upward-arrow sign, one red-and-white no-entry sign on the left, and one small green diamond sign on the right. Use saturated cyan-and-white color grading, crisp anime linework, glossy cel shading, high contrast sunlight, sparkling dust particles, motion in the hair, and a polished gpt-image-2 anime key visual style. Aspect ratio 9:16, clean composition, no extra characters, no text overlays besides blurred environmental signage.
