blender? apply a norm map and a disp map to the bricks, make the view match, use softbody on the carpet and let it drape itself onto the floor, make the tower cylinder have more polygons, the table too, get a pic of the walls and set it as the ref map for the chrome/metal stuff, or make them have ray reflection (the better choice) make the shadows soft and less blocky and work with the material on the table, it just looks very cg. All of this is minor stuff, so far, nice picture.
