Help with an 0C's Cutiemark!

[Freaky Dolphin 15]

Hello everybronie!!
I'm trying to give to my OC an adequate CM, but i don't sure of what could it be.
My OC is ( in my comic) the King of th Underworld, but his not really bad. He organizes the souls of the living and thinking beings among those who deserve punishment and no, it is also responsible for the Tartarus. His name is Shadow Mist.
Here is he in some of my art work: 
 

and here ( that CM is temporally and i dont like it)

In the end i would like your help, thanks.

Hmmm... Maybe i can be of some assistance. Im not the best artist in the world, but i could give it a shot to help u out. Is there anything in particular that ur wanting? Or are u still brain storming ideas for a cutie mark?

with souls and the underworld I think something simple

that shows this and is easy to draw would work so

I did a little research and found this which might
