well here is a new render, added some motion blur in photoshop. Finally used GI_Joe and didn't use the ceiling (thanks wicket) Mental ray is a whole different ball game - didn't have time to learn to use it and it's well slow for me
I like the look of GI_Joe as well!!
The room isn't finished yet - got a few more bits and pieces to add as well as different textures. Maybe a bit of rounding of corners.
The quality of this render is not v high - forgot to change the aliasing quality - DOH!!!!
