Skyborne Anime Biker in Ancient City

Create a highly detailed vertical anime fantasy illustration of {argument name="character name" default="April"}, a confident young woman riding a custom chopper motorcycle through the sky above a sunlit ancient Mesoamerican-style city. The composition is a dramatic low-angle view with the oversized front wheel dominating the lower left foreground, long chrome forks rising toward the center, high ape-hanger handlebars, a round headlamp, exposed engine, multiple polished exhaust pipes, ornate engraved gold-and-turquoise motorcycle bodywork, and the rear wheel partly visible under the rider. The rider has {argument name="hair color" default="light brown"} hair in a loose side ponytail with soft bangs, warm brown eyes, a faint smug smile, and a relaxed cross-armed pose while seated sideways. She wears an all-white decorated biker outfit: white jacket, loose white pants, wrapped white socks, dark shoes, and a long flowing white coat like a Japanese biker gang coat, covered with floral embroidery and vertical kanji-style lettering reading {argument name="coat text" default="明日天下"}. Behind her, tied to the motorcycle, place exactly 1 large transparent sack filled with many small dark metallic chunks, like rune metal ore. The motorcycle and rider appear airborne, backlit by a blazing sun directly behind the handlebars, with radiant beams, blue sky, puffy white clouds, and a distant fantasy city below. In the background include exactly 2 large stepped pyramid temples, many small city buildings, drifting dust or steam clouds, and exactly 6 red feather-like flying objects scattered in the lower sky. Frame the entire image with an ornate symmetrical border inspired by Aztec/Mayan motifs: gold, teal, and terracotta geometric patterns; exactly 2 stylized winged serpent/eagle creatures at the top left and top right corners; exactly 1 circular sun medallion centered at the top; exactly 1 circular emblem centered at the bottom; and decorative corner medallions. Use a luxurious illustrated poster style with intricate linework, warm golden highlights, reflective chrome, jewel-like ornamentation, cinematic lighting, dynamic perspective, and ultra-detailed anime rendering. Keep the mood triumphant, whimsical, and adventurous. No modern city skyline, no photorealistic faces, no extra riders, no extra motorcycles, no watermark.
