Use the provided image of the man with the black horse exactly as it is, keeping the man’s pose, facial expression, clothing, lighting, and the horse’s position unchanged. I only want you to replace the background.

Change the tropical background to the interior of a clean, bright horse stable with wooden stalls and black metal bars, similar to a professional equestrian barn. Include a long hallway, horses in some of the stalls, and the symmetrical stable layout.

The man and the horse must remain perfectly detailed, sharp, and untouched. Only modify the background to match the horse stable environment.
