Combining 2D & 3D Animation | After Effects Source File

There's not a ton of tutorials out there describing the workflow of combining 2D and 3D in animation form. I wanted to experiment a bit and see what I could do (even with my minimal knowledge of 3D!)

So with my tutorial series on YouTube walking through how I made this animation, I'm putting the full project file up to help other motion designers & illustrators learn too!
