I Little Thing I Would Like to Change.

If I had time to re-render my scene I would like to change the material that was applied to the window inside the room. When you look at the animation it looks like a skyscraper is sliding past the building as you're moving in the room.

This is because i originally applied a map to the envirnoment of the scene and made the window see through. The problem i had with that is that the image didnt look straight when looking out the window. After this I added a new material to the window, which had the skyscraper scene as a diffuse map and this gave a better look, at the time i forgot to remove the environment map and therefore i get this error when running the animation.
