first of all, the graphics seemed to be ok. they aren't that great, but at least you didn't use some lame stick figures.
but the rest of the flash is pretty dull. the animations look more than a slideshow than like a fluent animation, the text bubbles dissappear way too fast and why was the screen so small? this made the text even harder to read.
also, you didn't add sound to this and that is pretty annoying.
the plot itself was quite funny, but the presentation lacks quality.
add some sounds and make the screen size a tad bit bigger, so that one is actually able to read the text.
