Studio-Grade Two detailed multi-image prompts for layout and character scene

Prompt 2: the nine characters from the second attached image (a character sheet) spending relaxed time in the living room background of the first attached image, each sitting on sofas, looking at a photo hanging on the wall, picking up a book, or sitting on the floor chatting.

Prompt 1: stitch the attached files into a 3x3 grid into a horizontal landscape file, resize keeping the ratio so the long side after merging is 1400 pixels, output as JPG at 100% (highest) quality. Prompt 2: a living-room group scene composition.

Warm cozy indoor living-room lighting.

A living room interior used as the background.

Realistic multi-image composite / character-scene illustration.

Prompt 1 handles a 3x3 stitched layout output as a 1400px-long-side JPG at 100% quality; Prompt 2 places the nine characters relaxing in the living room. Tip: add a tiny size-reference object (a coin, a pen) to intuitively convey the subject's scale.
