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, same framing. Change ONLY the pose and expression: he gives a confident thumbs up with one hand raised near his chest, bright approving smile, the other hand relaxed. Vertical portrait from top of head to mid-thigh, centered, the thumbs-up hand fully inside the frame. IMPORTANT: entire background must be a single flat solid chroma-key green (#04ab50), completely uniform, no shadows, no floor, no props, no text.
