Very nice render, but something about it instantly screams CGI to me. I think its the over-use of the grunge textures on everything, on otherwise immaculate surfaces. No dustbunnies in the corners, nothing on the floor - it all just looks a little unnatural, that the level of wear looks artificially made - seems to lack a human quality to it. Hard to put my finger on it I guess.
But good work just the same.
Terry Gilliam's case against CGI was this - shooting things in-camera, be it a real city or a model or whatever, bears the imprint of many real people interacting with real things. CGI tends to be one guy an a cubicle, so everything has only the imprint of the one guy who built the geometry, painted the textures, lit the scene, etc. It hasn't been "handled" by anyone, and thus lacks humanity. I guess that's the vibe I get from this image - that it has the patina of age, but lacks humanism.
