Rob-o-Matic: Wallpaper Updates

In the shot above, I've attempted to give the effect of wooden paneling. I like the way the wallpaper looks but I feel like it may be a bit too much of the same pattern. I'd be happy to hear any feedback on the work so far. The pattern itself is a free wallpaper pattern from FreeGreatPicture.net. However I may have to play around with different colours because of how it's similar to the colour of my Robot.
