Doraemon Teaching Class

I want a hyper-realistic photo, but with a slightly surreal content. It feels like a child, after school, secretly peeking through the crack of the classroom door to see a magical scene: Doraemon is actually in an empty classroom, like a little teacher, seriously preparing for a chemistry class. The entire picture should be very realistic, yet filled with a fairy-tale warmth and wonder.

Content of the Picture

Main Subject: Doraemon himself, standing vividly in front of the classroom podium, rather than being drawn on the blackboard. He looks three-dimensional, with a smooth texture, as if he has walked out of the animation, yet perfectly blends into this real environment.
Character Details: Doraemon stands beside the podium, slightly turned, with a serious yet friendly expression, as if he is thinking about how to teach Nobita and the others.
One of his hands holds a small pointer, pointing to the blackboard behind him.
His yellow bell reflects a slight shine in the classroom light, and the four-dimensional pocket on his belly looks plump.

Background Details (Blackboard): On the blackboard behind him, there is a hand-drawn periodic table of chemical elements in various colored chalk. This periodic table looks like it was just drawn by Doraemon himself, colorful and with a bit of a cute style.
Different colored chalks (like yellow, blue, pink) can be used to distinguish different element areas, making the whole picture more vibrant.

Text: At the top or corner of the blackboard, in a cute chalk font, write the title: "Doraemon's Science Classroom."
Environment and Composition
Scene: A typical Japanese classroom, with desks and chairs neatly arranged, and the warm glow of the setting sun streaming through the windows, creating a quiet, warm atmosphere.
Composition: The aspect ratio of the picture is 4:3. From the perspective of a student's seat, Doraemon and the podium are centered in the frame.
Foreground: The very front of the picture can include one or two student desks and chairs to enhance the immersive perspective. On the podium, there can be a box of colored chalk and an eraser.
Style and Technical Requirements
Style: Photorealism. The key is the realistic environment and lighting, combined with the whimsical nature of the Doraemon character.

Lighting: Warm afternoon natural light streams in diagonally from the window, naturally illuminating Doraemon, creating soft shadows and highlights on his round body, giving him a sense of volume, and casting a faint shadow at his feet, making him appear more real.
Focus: The focus should be clearly on Doraemon, with the content on the blackboard also clear, but the foreground desks can be slightly blurred.
Absolutely do not allow!
Do not let Doraemon look like a plastic toy or model; he must be alive.

Do not include any other characters, especially Nobita, Shizuka, or others.
Do not make the art style look like an animation screenshot or pure CG; it must have a photographic feel.
The composition should be stable, avoiding strange low angles or fisheye lenses.
Colors should not be too bright; they should match the colors under real lighting.
