Very 2008-esque. Nothing too new to Newgrounds (or anywhere else on the internet) at this point. The animation was simple and I think it was my favorite part due to its old style nature, but the audio didn't match the mouth movement so well. The colors are not that great to look at.
You should look into some basic complementary colors and match them with your character designs.

Your next animation needs to be more original if you want to improve on your product.
