崩坏：星穹铁道-流萤·第01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). wearing a stylish fitted crop top paired with coordinated high-waisted tailored shorts, fully replacing the original costume, with no original clothing elements retained. without her original jacket dress, headband, ribbons, or armored elements for the selected outfit. cowboy shot, eye-level, knee-up framing, mid-thigh to head. showing a tsundere look, half-pouting and half-fond. framing the face with both hands like a picture frame. cleanly detailed, smooth rendering with soft gradients and clean flat color areas, minimal grain or noise, clearly adult character, balanced natural body and bust proportions, fashion-forward styling faithful to the specified outfit design.
