Harry Potter style grosse tête

High-quality stylized 3D CGI big-head cartoon render of Harry Potter, square profile picture composition, oversized head and small shoulders in a playful Pixar-style caricature. Head and facial features exaggerated while keeping him instantly recognizable: messy dark hair, round glasses, lightning-shaped scar on the forehead, curious and brave expression. Portrait framing focused on the large head with a small portion of the shoulders visible, wearing Hogwarts robe collar and tie. Smooth polished materials, glossy animated film shading with refined Pixar-style character rendering. Soft cinematic lighting creating gentle highlights on the glasses. Minimalist bright magical red background inspired by Hogwarts colors, clean composition optimized for social media profile pictures, ultra-detailed, no text, no watermark.
