This was really short, needs effort
You have a really short animation here, it also loops so thats an easy fix, i explain with more detail but basicly, it will stop the looping its called a "STOP-ACTION-CODE" you can do a search for it in the flash forums for help if you dont understand much about it, also you flash was way short you may want to think about adding more to it or making a number of short flashes so its not just one single one, thats an idea that you could try, The animation, was also too fast you want to slow it down just abit, also you should change up the "CONTENT" abit it might be abit much for some, so these are just a few things to think about, So think of new ideas, put much more effort and really put stuff into it like effects maybe a story of some sort and see what you come up with, good luck on your next entry.
~~THINGS TO IMPROVE ON~~
I would suggest to improve on the flash short you could add more shorts and put them all on one flash instead of just the one, but having alot in one flash would make it more entertaining, and make the flash longer with more to see, A short animation you have here, maybe abit too short i would say to improve on the flash as a whole either make this one longer with much more content or, add more shorts in here such as about 3-5 short short animatins that way it doesnt seem like a waste of one flash space and also you get more viewing for alot of your work instead of just one piece, These are just a few things that could help to improve on this.
A very short flash, had some off content but it could use some improving, i explained a few ideas hope that helps abit.
