Doraemon Teaching Class

I want a hyper-realistic photo with slightly surreal content. It feels like a child peeking through a classroom door crack after school and seeing something magical: Doraemon is actually in the empty classroom, like a little teacher, seriously preparing a chemistry lesson. The whole image should be very realistic yet filled with fairytale warmth and wonder.

Image Content

Main Subject: Doraemon himself, standing alive in front of the classroom podium, not drawn on the blackboard. He looks three-dimensional with smooth texture, as if he walked out of an anime, yet perfectly integrated into this real environment.
Character Details: Doraemon stands by the podium, body slightly turned, expression serious yet friendly, as if thinking about how to teach Nobita and friends.
One hand holds a small pointer, pointing at the blackboard behind him.
His yellow bell has a slight reflection in the classroom light, and his four-dimensional pocket on his belly looks plump.

Background Details (Blackboard): Behind him, the blackboard displays a periodic table of elements hand-drawn with various colored chalks. This periodic table looks like Doraemon just drew it himself, colorful with a slightly cute style.
Different colored chalks (like yellow, blue, pink) can be used to distinguish different element regions, making the overall image more colorful.

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

Environment and Composition
Setting: A standard Japanese school classroom with neatly arranged desks and chairs, afternoon sunlight streaming through windows, creating a quiet, warm atmosphere.
Composition: 4:3 aspect ratio. From a student's seat perspective looking forward, Doraemon and the podium are centered in the frame.
Foreground: The very front of the frame can include one or two student desks and chairs for immersion. A box of colored chalk and a blackboard eraser can be placed on the podium.

Style and Technical Requirements
Style: Photorealistic. The key is the wonderful combination of real environment and lighting with Doraemon as an anime character.

Lighting: Warm afternoon natural light streaming in from windows at an angle, light naturally falling on Doraemon's body, forming soft shadows and highlights on his round body, giving him volume, with a faint shadow at his feet to make him look more real.
Focus: Focus should be sharp on Doraemon, blackboard content also clear, but foreground desks can be slightly blurred.

Do Not Include!
Don't make Doraemon look like a plastic toy or model—he must be alive.
No other characters, especially Nobita, Shizuka, etc.
Don't turn the style into an animation screenshot or pure CG—it must feel like a photograph.
Keep composition stable, don't use strange low angles or fisheye lenses.
Colors shouldn't be too saturated—should match realistic lighting colors.
