Steel Train - You and I Undercover

Projects

I’m currently working on a project that will allow 3D models to walk along 2D images, as if they were inside of the painting/drawing/etc. What I am hoping for is a neat effect of bringing a feeling of reality to the depth of 2D artworks. Right now I’m curious as to what kind of artwork will look best with a 3D model walking around in it. Perhaps a painting, sketches, or vector art? What do you think?
