I'll give you some credit since this seems to be your 1st animation (as far as I know), but we got some problems here. The voice acting really needs to be improved on. I recommend you getting what's called Audacity. It's a free audio program that will help amplify your voices so they don't seem quiet, and it can get rid of those air buffs using Noise Removal. As for the overall art in general, that also needs to be really improved on. Granted everyone has their own opinions on what makes good art, but maybe some legit backgrounds would be nice for your animations instead of having one-colored backgrounds. And yeah, practice drawing your characters more because practice makes perfect. I know others may hate on you for this, but I hope that you get better in the future. I'm sure you have a lot more talent than you realized, it just needs to be improved on. Good luck!
