Short and a little crude
I think that it's a decent practice piece, which shows that you're willing to learn the tools that go with this fine program. You could certainly use subtitles, as this piece doesn't have the loudest voice acting and as a result, I found myself turning up the volume to hear the voices, only to have my ears raped by the sound of the gunfire. Balance is the key.
With the animation and drawing, you could use a little more time there, meaning zooming in and possibly using a smaller tool, to give a greater degree of control over what you're drawing, so that when you zoom out, it looks more rounded and a better quality image.
The shop keeper standing behind the counter, was he a midget, or was there something else there that I missed? It didn't seem right. Also, you don't need to drop hints like "This flash deserves a 5", as it's not even a subliminal message. More work on the animation will bring its own reward for you :)
Finally, with the change that hits the counter, perhaps just make it a denomination that is recognisable, as opposed to writing "change" on it. Why not have the voice actor do an impression of Home Alone's archive footage film, with the line "You can keep the change, you filthy animal"?
I look forward to seeing what else you can produce.
