I do my animations in Currently at adobe flash.
Yeah i know its old software and dead one but its not for me.
Sometimes Old software's is good ones so yeah.
For animations i plan hours of making them as an example one of my animations i planned 5 Hours currently and I'm working out that animation now i also mix symbol based animations for my Frame by frame animations so yeah but for motion tween not so much!
The rough sketch is usually red and later on its black i also use many different colors for sketching and making the animations so later on i just change outline colors for different color.
IF YOU HAVE SOME QUESTIONS YOU CAN ASK ME AND I TRY ANSWER SOON AS POSSIBLE.
