Here's another Lovecraftian being to add to this site; the Great Race of Yith. I have not yet read The Shadow Out of Time, but these guys are from that story. From what I know, they measure ten feet in height, lived on prehistoric Earth until the late Cretaceous, and mastered precognition (seeing the future) with the use of time travel. It may not be the best skin, but I know someone out there can do better, which I'm okay with.

The coloring is based on Michael Bukowski's interpretation of the Yithians. Go check out his blog, he has done interpretations of other deities and eldritch horrors, including those of H.P. Lovecraft.
