UPDATE (4/26/11): To everyone that has pointed out the hair color... Yes, i am aware that Finn has blonde hair, when this piece was done (FOR CARTOON NETWORK) it was not yet revealed the color of Finn's hair. In fact Pen Ward saw the piece and did not say that the hair color was incorrect, so maybe he wasn't aware of Finn's hair color either yet.
A friend of mine is working on the upcoming Adventure Time show for Cartoon Network and asked some folks to contribute to an art tribute thingy. This is mine...
Can't wait for this show to premier in March, it looks totally mathematical!
Read the artist's comment, simpleton. This was made before Adventure Time even aired and CERTAINLY before it was revealed that he had blonde hair. The creator of the show did not even know what Finn's hair color was. Maybe do some research before you write a comment. Also, learn how to spell, because you look like an idiot.
