From the prop Inside the Window:
The 2 windows at the back are window material 1 with the transparency set to zero.
The 2 windows at front are window material 4.
That creates the reflections as seen in the image.
Post work done was to darken the top 2 corners to focus your eye down to the characters.
Render was done in Poser Firefly.
