Doraemon's Secret Classroom

I wanted a hyper-realistic photo, but the content was a bit surreal. It feels like a child sneaking through the crack in the classroom door after school and seeing a magical scene: Doraemon actually is in the empty classroom, diligently preparing chemistry class like a little teacher. The entire scene must be very realistic, yet filled with fairy-tale warmth and wonder.

Screenshot contents

Main Subject: Doraemon himself, standing alive in front of the classroom podium, not drawn on the blackboard. It looks three-dimensional, with a smooth texture, like something out of an animation, yet perfectly blending into this real environment.
Character details: Doraemon stands by the podium, slightly tilted, with a serious yet friendly expression, as if pondering how to teach Nobita and the others.
He held a small pointer in one hand, pointing it at the blackboard behind him.
His yellow bell reflected slightly in the classroom light, and the four-dimensional pocket on his belly looked bulging.

Background detail (blackboard): On the blackboard behind him, there is a handwritten periodic table of chemical elements in various colors of chalk. This periodic table looks like it was just drawn by Doraemon himself, with rich colors and a bit of a cute style.
You can use chalk of different colors (such as yellow, blue, pink) to distinguish different elemental areas, making the overall composition more colorful.

Text: On the top or corner of the blackboard, write the title in cute chalk font: "Doraemon's Science Classroom."
Environment and composition
Setting: An ordinary Japanese classroom, with neatly arranged tables and chairs, the afterglow of the setting sun streaming in through the windows, creating a quiet and warm atmosphere.
Composition: The aspect ratio is 4:3. From the student's seat perspective, Doraemon and the podium are positioned at the center of the frame.
Foreground: At the very front of the frame, you can bring one or two student desks and chairs to make the perspective more immersive. On the podium, you can place a box of colored chalk and a blackboard eraser.
Style and technical requirements
Style: Photorealism. The key lies in the authentic environment and lighting, blending perfectly with the anime character Doraemon.

Light: On a warm afternoon, natural light streams in through the window, naturally shining on Doraemon, creating soft shadows and highlights on his round body, giving him a sense of volume. Shadows cast at his feet make him appear more realistic.
Focus: The focus should be clearly on Doraemon, and the content on the blackboard is clear, but the desk in the foreground can be a bit blurred.
Absolutely do not show up!
Don't let Doraemon look like a plastic toy or model; it has to be alive.

No other characters, especially Nobita and Shizuka.
Don't turn the art style into animation screenshots or pure CG; make sure it feels like a photo.
Composition should be steady; avoid strange low-angle shots or fisheye shots.
Colors should not be too bright; they should match the colors under real lighting.
