I have one of these drums although it is not made with skulls but beautifully turned wood. Thank god for modernity. The truth is the skulls used are more powerful magically if they are virgins who were murdered. I don't think I want that power on my hands. It was drawn with my copic multiliners and colored with prismacolor.
What I really love about this drum is it's purpose:
To summon the Buddhas and inspire them with SUPREME JOY!!!!
