A high-quality 3D chibi-style cartoon avatar of a cheerful sommelier, captured in a waist-up portrait shot. The character has large, expressive sparkling eyes, a gentle smile, and is wearing a classic black sommelier apron over a crisp white button-down shirt with a silver tastevin hanging from a chain around their neck. The character is holding a crystal wine glass by the stem, swirling a deep ruby-colored vintage wine, with a tiny, whimsical splash frozen in the air. The lighting is soft and warm, reminiscent of a high-end cellar, with cinematic rim lighting highlighting the character's hair and clothing. The background is a beautifully blurred, bokeh-filled wine cellar with glowing ambient candlelight reflecting off glass bottles in the distance. The rendering style is smooth, vibrant, and polished, utilizing 3D octane render techniques with subsurface scattering on the skin to give a soft, endearing glow. The color palette features rich burgundies, deep oak browns, and creamy whites, creating an inviting and professional atmosphere. The composition is centered, framed as a perfect circular profile picture with a shallow depth of field to keep the focus entirely on the charming character.
