Really Good, but I think you could do better.
Okay, I'm not one to judge as for im no game developer or flash animator (even though I'd like to be but I cant find a linux alternative to flash) but it seems to me that all of the fireworks are much too similar. if you were to observe a recording of an original display you'd notice that there are a varietyof different firworks. all of these appear to explode in the same way, despite the difference in color. but all I'm saying is the pattern becomes clear after 10-15 seconds. What Im trying to say is:
add some different explosions in and perhaps some different sound effects too.
However, the graphics are great and the explosions are realistic which is the exact reason I would like to see some variety in an animation like this. I really love your work even though I'm new to Newgrounds but I really enjoy your creativity and your ability to produce some amazing stuff. I hope to some day be able to create some work as good as yours.. just as soon as I find that alternitave to flash.
