So this is a concept paint over I've done of my garage. I rendered out my scene in Max using Mental Ray and used a combination of colour and texture overlays to give it some life. Professional racing garages like this are often absolutely spotless and kept in pristine conditions due to the extremely expensive equipment present and its' high standards. This can be a bit of a problem when creating interest in the scene. I have made the dirt in the garage very subtle because of this and this is the same when it comes to all of the objects scattered around. It's something that I'm going to have to pay close attention to when building my environment.
