Looks like an Ithorian from Star Wars. (...he stated obviously?)
I feel like this work makes a commentary on our sexual mores and the taboo nature of open sexuality and pornography. The alien identity of the subject kind of removes the sexual taboo from the title "Pornstar" and thus reminds us that sex, around which we've built taboos and an adult entertainment industry (among other things), is after all a simple biological function. Maybe I'm being too philosophical about it.
I love the idea of adding such personality to such strange characters. Going beyond that idea of "every picture of an alien is a soldier," and having pictures of criminals, diplomats, and hey, porn stars!
