Aw, these characters are so cute! :3 ..well, except for the stick guy; he's normal. :\
these are really cute, and all in all, the animation is not bad. Make a cute story with these, and you've got a good thing. :)
With that being said, please do not submit tests or incomplete items to the Portal. If everyone submits parts and bits and incomplete things, who will want to come to Newgrounds?
If you want feedback and tips, that's fine, but this isn't the best place for this. The Portal is for finished items. The Forums are what you want. Load this into your Dumping Grounds. It's the third icon from the left at the very top of the page when you're signed in. It looks like a bucket with an arrow pointing down. Once it's loaded there, copy and paste the link into the Forums (Community>Forums). (You can also put the link in a news post in your account, but the forums have more traffic.) That way, people can see it and give tips, which is what you want, but it's not in the Portal, filling your account with low scores or blams, which you don't want.
Good luck. :)
