Keep the EXACT same character, identical face, same short dark brown hair, same short beard, same beige/tan utility overshirt over dark charcoal t-shirt, same modern webtoon / semi-realistic anime illustration style and coloring. Change ONLY the pose and expression: now he is thinking — a curious, slightly skeptical look with one eyebrow raised, one hand raised to his chin/beard in a thoughtful gesture. Vertical portrait from top of head to mid-thigh, centered. IMPORTANT: entire background must be a single flat solid chroma-key green (#00b140), completely uniform, no shadows, no floor, no props, no text.
