Hi Steve,
Thanks for your reply!
For the first part (blue part) I think everything is done in 2D. I know that the snake seems 3D, but because of the graphics, the render, the lightning, I think it’s 2D. But a very nice and well-executed 2D but maybe not with AE. Maybe with Character Animator from AE, or Spine.
For the second part, it’s no doubt 2D illustrations with parallax layers. But if you can take a look to the shield at 51:00, I would say that you can’t do that with different layers in depth. The shield ‘turn around’ the soldier. And the shield is not a flat sprite/layer, it’s cambered. What do you think?
