崩坏：星穹铁道-流萤·第11期手机壁纸

vertical 9:16 mobile phone wallpaper composition, portrait orientation. A high-quality illustration featuring Firefly from Honkai: Star Rail (long silver hair with soft teal tips, bright teal eyes, gentle young adult woman). Use natural balanced adult proportions with an understated overall silhouette, without exaggerated curves. wearing a refined comfortably tailored sweater mini dress paired with sleek over-the-knee fashion boots and elegant cold-weather styling, fully replacing the original costume while retaining only identity-defining physical traits; do not retain original clothing, weapons, headwear, masks, armor, capes, wings, costume accessories, decorative props, companions, or signature ornaments. Use dense opaque knit with a comfortable fit, soft natural weight and gently hanging folds. full body shot, low angle looking up, dramatic empowering perspective. use a fresh independently composed framing; place the subject slightly left of center with comfortable breathing space on the right, while preserving the selected shot and complete framing. showing a radiant joyful expression. holding one open palm forward in a gentle wait gesture. cleanly detailed, smooth rendering with soft gradients and clean flat color areas, minimal grain or noise, clearly adult character, fashion-forward styling faithful to the specified outfit design.
