Not bad for your fisrt movie!
I am amazed that this is your first movie. you have much potential to make a badass catoon. however this one lacked good sound "mixing" (make all the volumes around the same tone) and was not very funny. That one background got boring after awhile. The animation was jerky.(which can be fixed by adding more Frames Per Second and get used to that) And you could have given more detail as to what was happening. other than that it was pretty good. keep improving your animating skills and i hope to see more.
