I came across this Space Skeleton by Antoine (AKA Ybliss) while wandering through Flickr. There are times when a image just reaches out and grabs you, but you can't quite articulate 'why'.
The starkness of the white skull against black, the great parts usage to create shape and texture, paired with the back drop all come together nicely. Clean, simple, effective.
