This is something I was playing around with for a while, mainly focusing on lighting.
Pretty basic stuff here…
Wall texture made in GIMP, just some clouds blurred and pulled. Just used it as a bump here.
The picture on the wall was made by me in Vue 8xStream a while back, “clothified” in GIMP.
Sticks are bezier curves. Small amount of cloud bump added to the floor.
Lights are all areas, only the one on the left has shadows turned on, the others have no shadows and specular turned off so they don’t show anywhere on the glossy stuff.
Environment lighting on .3, sky color(very light blue)
Rendered in Blender internal, no nodes/compositing, no post-pro.
Really, that’s it, hope you dig it
