Stylized Modern Vector Portrait Template

Create a high-detail stylized digital illustration of a young man wearing a plain black t-shirt; the art style is smooth, modern, and vector-like, featuring clean shading, crisp edges, and soft gradient transitions; the subject has a calm and focused facial expression while looking slightly to the side, conveying subtle confidence and introspection; lighting is soft and even, enhancing facial structure without harsh shadows; the background is minimal and uncluttered, set in a soft grey tone to maintain a professional and neutral aesthetic; the final portrait should emphasize clarity, polish, and contemporary character illustration quality, aligned with [VISUAL STYLE], associated with [BRAND OR PROJECT NAME], and rendered in [RENDER QUALITY].
