New Factory Floor Built

I have a new digital background prepared that I'm considering for use in the one wide angle greenscreen shot of the factory floor. Below is the image with the live action action composited on top. The background started as a Maya render and then moved into Photoshop to get dirtied up and some irregularites added in to make it less symmetric. The background isn't detailed enough to hold up to a careful eye, but the shot is only five seconds and animated crates moving along the ceiling should create enough movement to keep the eye engaged.
