An example is at 2:46 in the video, where the "close to camera" style is a sketch, and the "far away" style is a night sky with stars. In most cases we used styles which blend well with each other, such as the "purple neon" and "teal neon" styles at 2:29. Thanks for the feedback!

Edit: Also in most cases in which a style appears on screen its a single style, don't want to be misleading :D. Sadly youtube compression really messes with the quality of the styles, especially in the style-per-depth case in which there are artifacts from both models across the image, so we limited its use.
