character: firefly_(honkai:_star_rail), copyright: honkai:_star_rail firefly_(honkai_star_rail), long light gray hair with teal ombre tips, eyes a mix of deep ocean blue and sunset pink — no headband, no green feather hair ornaments, keep her natural hair and eye color exactly as her canon design. Important: do NOT use her default in-game SAM mecha armor design. She is wearing a completely different custom sci-fi bodysuit described below instead. Wearing a black and white form-fitting sci-fi combat bodysuit with glowing neon-green accent lines running along the seams and joints, a deep plunging V-shaped neckline cut low down the chest, a large angular white shoulder pauldron on one side with black paneling, the opposite arm sleeve cut open exposing bare skin at the forearm, segmented armor plating at the knees and thighs, black mesh fishnet-like underlay visible beneath the suit panels, fingerless tactical gloves with a glowing green LED strip. One hand holding a sleek black and white weapon or device angled downward in front of her, the other arm relaxed at her side, standing upright with a confident posture, head turned slightly to glance toward the camera with a faint self-assured smile. Medium-full shot, camera at eye level, shallow depth of field with the background softly blurred. Cool blue-white ambient lighting from overhead, soft rim light along the edges of the armor and hair, reflective highlights on the glossy suit panels. Clean anime illustration, crisp sci-fi mecha-style linework, sharp cel shading with glossy specular highlights on the armor, cool color palette of black, white, and neon green. Background: a blurred futuristic hangar or tech facility interior with soft ambient blue-white lighting, roughly 55% of the frame given to the character to keep the detailed suit design prominent.Phucquanbmt11
