Same man as in the reference photo (same face, curly dark hair, short beard, dark olive-green overshirt over black t-shirt). YouTube thumbnail pose: excited confident grin, eyes wide, pointing with his right index finger toward the left side of the frame as if showing something huge behind him. Waist-up, body turned three-quarters. Bright studio key light, crisp sharp detail, high contrast. Background: perfectly flat solid pure green (#00FF00) chroma key, no shadows on background, no props, no microphone.
