Social Media Post - Summer Idol Catgirl Festival

Create a vibrant vertical anime illustration of a cheerful catgirl idol performer at a huge outdoor summer music festival. The main subject is {argument name="character name" default="a pink-haired catgirl idol"}, shown from a low-angle three-quarter view in the foreground, smiling brightly at the viewer with red eyes and short fluffy {argument name="hair color" default="pink"} hair, black cat ears with pale inner fur, a small yellow star hair clip, and a dark cat tail curling behind her. She wears a Japanese sailor-style school idol outfit: cropped white blouse with dark navy sailor collar and sleeve trim, orange necktie, dark pleated mini skirt, and black fingerless gloves. Her right hand is raised in a V peace sign near her face, and a black stage microphone on a stand sits close to her on the right. Behind her is a massive festival crowd waving glow sticks, colorful confetti in the air, palm trees, stage trusses with bright lights, and banners reading {argument name="festival text" default="SUMMER IDOL FESTIVAL"} plus vertical flags that say “IDOL!”. Use a dazzling midday summer sky with saturated blue color, fluffy clouds, lens flare, sparkling highlights, dynamic motion, vivid rainbow festival colors, glossy high-detail anime rendering, dramatic backlight, sharp facial detail, and energetic idol-concert atmosphere. Vertical 9:16 composition, polished Pixiv-style illustration, no watermark, no extra characters in the foreground.
