Diamond Sword was the first Minecraft song that I wrote. Everyone I played it for said it was catchy. All my sons friends were singing the hook for for weeks after hearing it only once. That is definitely the mark that you have a catchy tune.
I looked really hard for a good animator. I found Francisco Novero. Franciaco lives in Manila Phillippines. There was a few set backs in completing the animation. Besides having to reformat his computer there was a major flood that sent water in his house up to his knees! Despite all this, he managed to complete the Minecraft animation in about thee months. Franciso is an extremely talented dude.
