OOOOoooo thats silky smooth

Wow! I never imagined I would receive such positive responses! I'm utterly thankful, got that animation surge crawling up my spine once again. Expect more! :D

Dayum son, that was awesome! keep up the good work :D

yet again, thank you all, I'm still overwhelmed by the feedback! :P
As for tips... There is alot of thinking when it comes to animation, because there is no physical world like the one we're in that helps with certain things like gravitation, you'll have to think out every thing yourself. For me the biggest problem is a steady hand when I draw. Just figure out before you put the pen on the paper what you are creating, the basics evolve around something we call "easing", which is the acceleration of... for example the limbs. Use the shadow tool to carefully make sure the space between the shadow and the drawn figure makes sense. A falling object speeds up until a maximum speed until it hits something, then it might bounce a little, and it should bounce less and less, which means the space between the shadow of the bouncing object minimize gradually. Then you put that knowledge into other things, bah my english sucks.

I like it, the movements are well eased. Keep it up!

Do you redraw the stomach part each time or make it into a movieclip and only redraw for bending?

Thank you thank you :D
I draw everything for every frame, except if the character for instance is just standing there breathing. Then I might move the body and legs as one, the head alone, and maybe one arm or two, it depends. But if the characters are in constant movements, everything is drawn :)
