New York 1854 Concept art

A concept art piece I did for an Indie film project, pretty much a paint over a 3D Rendering, lately my approach to Concept art is to make them look more like a part of a film than just a painting or sketch, I tend to use "optical dirt" such as bloom , lens distortions, glares, overexposure, chromatic aberrations, film grain and so on so the clients feels the painting already forms part of the film.
