Kawaii Academy Acrylic Sign Portrait

Create a high-key vertical studio portrait photo of an adult Japanese woman standing against a plain soft light-gray background, framed from head to upper thighs. She has a short wavy bob haircut with black roots and vivid electric-blue dyed ends, straight bangs, pale blue translucent square glasses with exactly 2 lenses, and a gentle closed-mouth smile while tilting her head slightly. She wears a colorful one-piece swimsuit covered in cute kawaii sticker-style motifs such as bunnies, stars, strawberries, clouds, hearts, flowers, and pastel cartoon shapes. She holds a clear rectangular acrylic sign horizontally in front of her torso with both hands visible at the left and right edges; the sign has exactly 4 small round metal fasteners, one near each corner. On the sign, place a bold pop-idol Japanese logo with thick white and hot-pink lettering, black shadow outlines, sparkles, bubbles, lightning bolts, hearts, and stars; the main text should read logo_text with a small English subtitle underneath reading subtitle_text. Use glossy magazine-quality photography, soft even lighting, realistic skin texture, shallow depth of field, crisp focus on the face and sign, playful Harajuku/kawaii color palette, no watermark, no extra people, no clutter.
