Okay, now this HAD to be a reference to "Adventure Time!". Then again, those clothes are kind of standard. Anyway, this was a really good art piece. I especially like how there's so many stars shining in the sky like diamonds as the song goes. It's also great to see how the dear (or whatever that is) has a rather serious concern on his face. It contrasts well with the utter insanity that the boy feels.
I can't help but notice all the little details. Like in the back, there's some shadow effect or something going on with the boy's tail coat (tail coat, what?). The colors are fantastically vibrant and bright. I guess it's pretty silly, but it still comes off as pretty awesome. We all wish we could do this.
