A young man standing confidently, wearing a simple yet stylish T-shirt under a crisp white lab coat. One hand is casually tucked into his pocket, while the other holds an object, such as a pen, a book, or a folded paper, adding personality to the composition. His expression is poised and professional, exuding a sense of confidence and approachability. The background is minimalistic and clean, ensuring that the focus remains entirely on the subject without distractions. The color palette is soft and calming, using neutral and muted tones that are easy on the eyes. The details are meticulously refined, from the natural folds in the coat to the realistic lighting on his face, creating a polished and high-quality final image.
