Modeling, materials, lightning and render in Blender.
Only import is the skull from Renderosity (see source 1) and the wallpaper texture from deviantArt (source 2).
Minimal postwork to smooth the image a little with a minimun amount of blur.
Ok, my last try to get a decent lightning. This time I watched at it in two different screens before posting. Thanks to all for your comments. (5 years and 1931 days ago)
