I think you did a very artistic approach to you. I had no idea that Reincarnation could be anyone's childhood. Dang, I feel old. What I like most about this is how you omitted all the black lines. It seems to be a lot more like a chalk drawing than a painting-esque picture. The shading is done quite masterfully.
There has to be a name to this character. It seems like he has four eyes with how the light emits from them. Four eyes, that's something I haven't heard in awhile. It's great how just a single character on a picture can look so good. He's as sinister as ever.
