Thanks, Mr. Vulture! Though I enjoy and appreciate all feedback, it's quite rewarding when people receive the ideas as I meant them to be taken. It often seems the more alien and un-relatable the better as far as beings from other dimensions go.
This painting was for the Lovecraft film festival, so the only real requirement was that it had some connection with film or theater. It's sort of a joke, but the idea that it is some form of extreme documentary-making. My thoughts were that they might just be recording her, but I like your idea that they are trying to glean some wisdom via conversation. I actually painted the crew and shub-niggurath separately and photoshopped them together, so there are two versions (with and without crew).
