I liked the art in this and the idea was a good one. But to get a 5 star, I would've liked to have seen a little smoother animation, and a little stronger script writing. If the main character was showing he had to pee really bad at the beginning (thus giving him a reason to pee there) it would've been a lot more humorous. Also while in the jail, again if you could show the main character having to pee once more but then realizes there's no toilet, the comical delivery would've been a lot stronger.
Other wise this has a lot of potential and keep at it!
