Overall, very good. I like that you kept things appropriate(there's just too much garbage on NG nowadays). Your character designs are very complex, and the colors are very appealing to the eye.
However, your storytelling skills fall very flat. I'm not so sure I understand what just happened, actually. I didn't see much of a storyline, much exposition, climax, or resolution. For instance, why was that guy trying to take over(...rob?) that store. What's the relationship between the antagonist and the protagonists? I suppose I have to give you leeway, since a lot of the plot holes seemed to have been intentional. Although, it didn't seem to have that comedic effect you were looking for.
Please, don't think that I'm hating on you. Certainly not, I'd just like to see a story more fitting of your level of artistic ability.
