Woah dude, that's pretty fluid and the movements are correct but why dont you make the same anim with human anatomy?

Thanks, and the reason why I don't is because I don't even know anatomy of the body. lol
I guess I can learn ;o

He's a heavy little guy isn't he?

I know the Flour-Sack practice is something that seems overrated.
But I recommend it for practice on Mass and Weight in a 3D space, two very important things that take play more outside of stickfigure animation.

If you're having trouble finding 'fullbody' animation practice material and reference, look up Chraracter Animation.
There's a whole world of information out there from super complex to ridiculously simple.

you should really do more of this, seems you have the hand of it.
only thing is, maybe it was alittle too fast, try slowing down the frame rate a bit and add a few double-frames
other than that, good job, i expect more like this from you :)
