Modern webtoon / semi-realistic anime illustration of a friendly confident young man, about 28 years old, short dark brown hair styled up, neat short beard, warm light skin. He wears a beige/tan utility overshirt with chest pockets, open over a dark charcoal t-shirt. Clean cel-shading, smooth soft gradients, crisp line art, high quality digital illustration, vertical portrait framing from the top of the head down to mid-thigh, body centered. Pose: looking at camera with a warm approachable smile, one hand open with palm up in an explaining/presenting gesture, the other arm relaxed. IMPORTANT: the entire background must be a single flat solid chroma-key green color (#00b140), completely uniform, no shadows on background, no floor, no props, no text — only the character on pure green.
