Demonic Seal

This is another tattoo idea I designed for one of my stories. It is meant to be tattooed on the stomach of a race of people born from demons as a conduit and controller of the demonic powers inside them. It is paired with the Angelic Seal, the key to the keyhole in the center.
The writing along the outer circle are symbols of my own creation. They name the 3 prime demons responsible for these people's existence, and hence are revered as gods. Starting from the top and moving clockwise, they are Kahrnic, Xoan, and Te'Rani. The writing in the center circle reads "Outcast."
If anybody is crazy enough to want to get this as a tattoo, please let me know! I think it would be awesome, but I don't think I have the money, nor the tolerance for it, lol. Otherwise, please give me credit/ask permission before using this for anything.
Thanks!

EDIT:
Turns out was awesome enough to get a tattoo of this piece with some slight changes done. Looks pretty sweet, so check it out!
