Very good first start...
Your first try is a lot better than a lot of people's flashes after a long while, good job. The graphics were, to me, the best part of the flash. I like the way everything was well drawn and really simple, it makes you focus on just what is happening. Style is nice also, with the black and white and the no background. Simplicity is what makes this good. Sound was to me the weakest point, I mean the pan-flute music was well-fitting but the fly buzzing was a bit irritating. Correct me if I'm wrong but that was just you buzzing into a microphone right? If so, you probably shouldn't have done it so loud. Lastly, the humor was nice. I knew what was going to happen but not when which is very good on your part. I was just watching and knowing it was eventually going to happen but a fly came out so I thought it'd be after this but then, "WHAM" it happened.
Overall, it seems like you got talent in Flash and I hope to see more. Work on sounds and you'll be one of the better Flash artist. I'd really like to see more done with these characters, especially the cool little girl. I'll check out your site until then ;)
