Well it's not bad.
But the only thing that loops is the audio. It would have been a bit better if you had him loop along with the voice.
Try putting effort in your animation. You shouldn't just want an easy quick flash on Newgrounds. I know what you can do, I know what you are capable of.
I would like to see a flash from you that's at least 30 seconds long. If you need any help/advice then don't hesitate to ask. I will even do voices if you need them. All I want from you is a flash that doesn't take you 30 minutes to complete. More like a few days of hard work.
