Here's my project from the course lessons I've created. In this short video, I also duplicated the project once I was done with animation and added the Cel Renderer effect. It's in the same place where we added Ambient Occlusion in the render settings.

I used this duplicate project with the wireframe rendering effect as another layer in After Effects with a track matte to reveal from wireframe the shaded version of the model beneath in the layer stack right before the animation begins.

I look forward to seeing what you all create and please share in the course project like this:
