roco43 has a gift for creating aliens and their environs. His work reminds me of the great sf covers of the 50's and 60's. In his Outer Limits 11 9 (a reference to the classic sf tv series) his long, lanky alien would fit right in with the monsters/aliens of that show. I also love the color pallette which is slightly deserty but with eerie coloring. The framing of the alien with an omimous bloated moom adds to the overall sense of strangeness.
