Good try.
It's only five seconds of animation. That's not gonna cut it for a newgrounds submission frame by frame or not.
Nice drawing style and well animated but you might want to work on a movie of more worth than just a brief blip on the screen. I give you props for effort but you failed at execution.
Next time make a full 60 second movie or just simply more than 15 seconds and you'll get a better score.
Keep flashing but work on making longer movies.
