Doraemon teaches a lesson.

I want a photo that is extremely realistic, but with some surreal elements. It feels like a child coming home from school and secretly peeking through the crack of a classroom door to see a magical scene: Doraemon is really in an empty classroom, acting like a little teacher, carefully preparing for a chemistry class. The whole image should be very realistic, yet filled with a warm and surprising fairy-tale atmosphere.

Image Content

Main Subject: Doraemon himself, standing alive on the front of the podium, not drawn on the blackboard. He looks three-dimensional, with smooth textures, as if he had stepped out from an animation, but perfectly integrated into this real environment.
Character Details: Doraemon stands beside the podium, slightly turned to one side, with a serious yet friendly expression, as if thinking about how to teach Takahashi and his classmates. One of his hands holds a small pointer, pointing at the blackboard behind him. His yellow bell has a slight reflection under the classroom lighting, and his four-dimensional pocket on his belly looks full.

Background Details (Blackboard): On the blackboard behind him, there is a hand-drawn periodic table of chemical elements in various colored chalks. This periodic table seems to have been just freshly drawn by Doraemon himself, with rich colors and a slightly cute style.
Use different colored chalks (such as yellow, blue, pink) to distinguish different element areas, making the entire image more colorful.

Text: At the top or corner of the blackboard, write the title in cute chalk font: "Doraemon's Science Classroom."

Environment and Composition
Scene: A regular Japanese classroom with neatly arranged desks and chairs. The remaining sunlight from the window shines in, creating a quiet, warm atmosphere.
Composition: The image ratio is 4:3. Viewed from the perspective of a student's seat, Doraemon and the podium are centered in the picture.
Foreground: At the very front of the image, include one or two student desks and chairs to give the perspective more immersion. On the podium, place a box of colored chalks and an eraser.

Style and Technical Requirements
Style: Photo realism. The key is the realistic environment and lighting, combined with the magical presence of the anime character Doraemon.

Lighting: Warm afternoon natural light comes in from the window at an angle, naturally illuminating Doraemon. Soft shadows and highlights are formed on his round body, giving him a sense of volume, and casting a faint shadow under his feet, making him look more realistic.
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 Include!
Do not make Doraemon look like a plastic toy or model; he must appear alive.

Do not include any other characters, especially Takahashi and Shizuka.
Do not make the style look like an animation screenshot or pure CG; it must have the feeling of a photo.
The composition should be stable, avoiding strange low angles or fisheye lenses.
Colors shouldn't be too vivid; they should match the colors under real lighting.
