Add classic Disney-style cartoon characters to a photo

Image prompt: Add 2D cartoon characters from a classic jungle-adventure story (a bear, a panther, and a snake) in classic Disney-style 1970s animation, with smooth lines, soft shading, and rounded features. The characters should look hand-drawn and slightly stylized, interacting with the subject in the image. Blend them seamlessly with realistic lighting and shadows so they feel part of the scene while still clearly animated. Keep expressions lively and charming. Don't make any changes to the subject's face or clothes. Maintain cinematic composition and subtle film grain, 4K. Video prompt: The cartoon characters move slightly, the subject is not talking, and is looking at the characters.
