I made the floor, wall, desk, mug, poster and piece of paper using Carrara 6 Pro and Hexagon 2.5.

Image rendered in Reality/LuxRender using Porta 800CD film, two mesh lights, one on top/right and one top/behind the camera and one IBL called "Living Room" from the HDR-VFX Promo Library at http://www.hdrlabs.com/sibl/archive.html (they're near the bottom). Postwork done in Photoshop Elements 9.

Thank you for all the comments and favorites on my last uploads!
