Advanced AI Prompt for Anime-Inspired Professional Mascot Sheets

Act as a Lead Animator in Tokyo. Craft a highly detailed, production-ready character design model sheet strictly adhering to the [ANIME_SUBSTYLE] (e.g., 90s Cell Shaded, Studio Ghibli, or Modern Shonen) aesthetic. The character represents a driven, creative professional. Facial architecture must feature [EYE_SHAPE] eyes, and they must be wearing or holding the [SIGNATURE_ITEM]. The sheet must be arranged as an animation studio reference guide including: A static T-pose front view, a highly expressive 'shocked/sweatdrop' face, a 'determined action' pose, and a casual walking cycle frame. You must ensure that the geometry of the hair spikes, the exact placement of eye highlights, and the physics of the clothing folds are mathematically consistent across every panel. High-quality cel-shading, crisp un-aliased line art, stark white background.
