Its ... ok but, umm it could have been a tiny little bit more tidy and detailed (backround, smaller brush, shading etc.) . Also you might want to look at some lip syncing tutorials but I do like the idea with the story and the voice isn't to bad.
Because this is your first one and im asuming you havn't done much on what your using i will give you a 3 .

Aaaaadventure time!

Made me smile. Since you admit it's your first tablet effort, I can give you seven stars, and a vote of 4. The Audio was okay, but the quality could improve.
