In collaboration with Natalia Banaś, we made this animation. She was an illustrator, my role was to animate.
I used a lot of techniques to finish it. I added some depth in 2D scenes. It helped me to achieve possibility to move camera in z axis in 2d animation. Also I make rigs for all characters. From simple to main haracters. Main haracters have also face rig done by Joystick&Sliders, and lip sync.
