Elegant White Gentleman in a Cartoon Classroom

A cartoon-style illustration of an elegant White man in a classroom. He stands at the front in a tailored navy suit, crisp white shirt, and a slim tie, with a confident, warm smile. The classroom is bright and inviting: a chalkboard with simple equations, neat rows of desks, books and pencils on the desks, colorful posters on the walls, and large sunny windows. The art uses rounded, clean lines and a soft, vibrant color palette to create a friendly, approachable mood.
