I don't know. I can't see any render intensive character there. Tina doesn't have displacement map. All I can see to her is a texture, normal and a bump map. They don't even using Sub-surface Scattering Shaders. Although I can't tell what type of renderer they use on rendering cg arts. Besides, they are using a beefy pc to speed up rendering images.

Animating a chracter is kinda maybe a little time consuming.

Most of the background are matte painted mostly based on real images that they photoshoot. So probably they should be a little faster when it comes to making a background.
