Weird Shadows

First thing I did was create a black background image about double the size of the source image(zebra stripes)

I then added the zebra stripes source image on top of the black image(layer 1), I then changed the perspective and changed the opacity to 34%.

Finally, I opened the doorway source image and cropped down to my liking. I then added it to the image(layer 2). Once on the background image I changed the opacity to about 30% and lined it up with the new perspective of the zebra stripes. Once lined up, I erased the unwanted portion on the zebra stripes. I then changed the opacity back to 100% and used the burn tool(highlights) and burned around the bottom of the chairs to blacken the floor out.
