A hyperrealistic photo, surreal scene of Doraemon preparing a chemistry lesson in an empty Japanese classroom. Doraemon stands three-dimensional and textured beside the podium, holding a pointer towards a blackboard with a colorful hand-drawn periodic table and title "Doraemon's Science Classroom". Warm afternoon sunlight streams through windows, casting soft shadows. Focus on Doraemon and blackboard, foreground desks slightly blurred. 4:3 aspect ratio, student's perspective view, natural color tone, creating a quiet, warm, and wondrous atmosphere.
