For a first time, quite impressive
I really like what you've got going here. A enjoyable art style, likable characters, and what looks to me like some genuine originality.
As was said by others, the frame-rate was a little low. A person can really be drawn into an animation if the movements are fluid, And that's something you can definitely do.
The characters, for the short time I could see them, were enjoyable, and they had a certain originality to them. Now admittedly when I watched this, I ended up thinking of Kung Fu Panda, and some of the kids shows on TV that feature martial art practicing animals. So the subject matter isn't really original. But the way in which you've designed your characters is. That's definitely a good thing, because it can save the concept from being to boring due to a overused subject matter. At the same time, if you simply find a less overused subject matter for these characters, or even design some new characters, then you could have something genuinely one of a kind.
If you're looking to animate in the long term, then I'd say you've got a good future ahead of you. Keep up the good work!
