Good.
It made me almost laugh at least once (the part when sonicky was singing that song, or, just saying the lyrics), but the voices are just recordings from a microphone, sped up with the computer's sound recorder. You could improve on the voices, like talk a little deeper when you start recording, and make sure none of your recordings have the sound of you breathing into the mic. Now I can imagine this turning out hilarious and very well done, but you have to improve some more before that can happen. I've seen some people who can pull off sprites well, and you can be one of them if you just keep making flashes, the skill will come naturally. Just aim towards making the voices believable, and you'll be in the right direction for improvement.
