This is a really good art picture. I don't know exactly why, but it seems like something that would be on the show "Adventure Time". Granted, I haven't seen any episodes of that except for the pilot episode. Anyway, what is so nice is how there's a lot of detail put into all of his body parts. This horns seem like they're staring into some deep chasm. It looks like it's forming some deep vortex of which there is no escape.
There could have been a background. Then again, it does contrast well with how colorful the character is. It looks like his eyes are practically melting off his face. A lot of old people tend to look that way. His legs/feet look like they're too weak to even support his body.
