HI, everyone, I will explain a some off simple points for the character animation.
1.)The animation is nothing but combining a sequence of drawings. This we can understand much more while in practices.
2.) Character animation mainly depends on our creativity only like a simple logic is how we act in our daily life, how we talk to others, How we walk, How we feel, How we react, How we express, How we move for every reaction like so many things are there that we can learn in our self things happens in our daily life.
3.) You can watch it online for the reference of above I said, and you can feel those things while watching.
4.) Keep on do plenty of drawings whatever it may no matter but please practice on the system to draw something new, something creative.
