This animation series I created for practice in animation principles.
Runing in 14 frames (24fps).
As refence I use this web site and this book “The Animator’s Survival Kit” by Richard E. Williams.
And I watched a lot of videos referens on YouTube.
If you want to know how to animate from scratch watch Digitaltutors video course.
From this course I got very helpfull script for mirroring pose. This script speed up my work.
