After the final artwork, I love to manipulate things. In this case I really like both the variations, made on the "Roman ionic desk" illustration. The black & white version really turns it into the highest level of photo realism: a bit of overexposure, depth of field, film grain, dust and particles really obliterate the CGI technique transforming it into something so real.
To the opposite, wireframe version in the second shot tells so much about mesh geometry structure and 3d model quality. And, in this case remeshing process was quite a long work.
