The artist specializes in surrealism and has a rather large gallery of phantasmagoric images (see the links above). He also has a very philosophical approach to art (which I see as a bad habit of needlessly overcomplicating life, but that's just me!). It's not rare for his images to have long and thoughtful comments, on DeviantArt especially.
Here are a few of my personal picks from Robert's gallery:
|Microbia 1, in Blue|
|Zoooids - Underworld II|
