Stylized Nano Banana Prompts

$A crowded Beijing subway car, but all the passengers are mythological figures (such as Sun Wukong, Zhu Bajie, etc.). On the rolling display at the carriage connection, red text reads: “Attention passengers going to the Western Heaven to fetch the scriptures, the next stop is: Gao Laozhuang.” On the glass of the train doors there is a warning sign: “Forbidden to cast spells inside the carriage.”

$Please stitch the file I just attached into a 3×3 grid to make a horizontally long file. After merging, resize it so that the long side is 1400 pixels while keeping the aspect ratio. Set the quality to 100% (maximum quality) and output as a JPG. Using the background from the first attached image (living room), place the nine characters from the second attached image (the character sheet) so they are spending time peacefully in the living room, for example sitting on the sofa, looking at the photos on the wall, picking up books, sitting on the floor and chatting, and so on.
