Confident Latino Mentor in an Old-Classroom Oil Painting

An oil painting of a confident Latino man standing in a classroom. He wears a crisp white shirt with the sleeves rolled, a charcoal vest, and dark trousers. He exudes authority and warmth, with a calm, assured expression and a slight smile. Pose: arms crossed, feet planted, looking directly at the viewer. The classroom has wooden desks, a chalkboard with faded writing, a globe, maps, and a vintage clock. Warm afternoon sunlight pours through tall windows, casting golden highlights and soft shadows. Painterly brushstrokes, visible impasto, and rich textures in earthy ochers, burnt sienna, deep blues, and greens. The atmosphere is noble and educational, reminiscent of 19th-century academic portraits but with contemporary realism.
