A pretty funny and pretty clever little series of gags. I'm glad you gave up on the voice-acting you used in previous shorts, it wasn't working out. Maybe some day you'll get some better recording equipment and some decent actors, but until then you're best sticking to silent movies.
Writing was a definite step up from earlier stuff as well. I don't know if it's a fluke, or if you've just learned over time, but this is the only short of yours I've seen that is both clear enough to make sense, and complex enough to be interesting. "Step sleeper" was too simple to be interesting, and "Do I smell Chocolate" was too obtuse for me to get the joke. But you nailed it on this one.
Your animation is good, not fantastic, but definitely easy on the eye. Maybe try to shoot for more fluidity, up your frame-rate a bit. Your art-style isn't quite there yet, I think. Where characters are concerned you probably just need more practice and more time to develop your style, but I think you're particularly at backgrounds and non-living objects. They're bland and frankly a bit half-assed looking, and your perspective is off in a lot of scenes. I'm not an expert, so take my advice with a grain of salt, but I think they also tend to be very empty. A lot of empty space with not much to fill it up, which I guess is a composition problem.
So in summary I think this flash shows nothing but improvement over your previous stuff, but it's still lacking in a lot of areas.
