It looks good, but it's way too short for submission. The sound effect could be improved so it sounds smoother and more realistic.

Your animation is about 1 second long! Please don't submit small, pointless items. Your submission should have characters and a plot and music, and should be finished before you submit it. Make it a whole, complete, finished item that's really good before you submit it. This is good, and it has sound, but there's no story, no plot, no length, no point to the submission. You did good on this, but it's nowhere near what it needs to be in order to stay here on Newgrounds.

Don't upload unfinished productions to the judgment zone. Rather upload them to the dump and post them in the forums if you want feedback. Besides that, there was nothing impressive about this animation, as is the same with just about any flash movie in which the graphics are based upon already existing sprites. The sound effect is also too loud and it cuts off too abruptly.
