A hyperrealistic photo, surreal scene of Doraemon preparing a chemistry lesson in an empty Japanese classroom. Doraemon stands three-dimensionally and vividly in front of the podium, with a serious and kind expression, holding a pointer towards the blackboard. The blackboard features a hand-drawn, cute-style periodic table in colored chalk, with the title "Doraemon's Science Classroom". The classroom is ordinary but warm, with soft afternoon sunlight streaming through the window, casting gentle shadows and highlights on Doraemon. 4:3 aspect ratio, shot from a student's desk perspective, focus on Doraemon and the blackboard, foreground desks slightly blurred. Natural, realistic colors, avoiding overly vibrant tones, creating a magical and cozy atmosphere.
