3D backgrounds in the works (Patreon)

The image is a screenshot from Unity showing off the outline shader I've been working on and it was a test to see if it looks like a drawing and I'm happy with the results. I quickly whipped up a 3D model of Quagmire's house just to work with in Unity. I'm still trying different methods for outline shaders in Unity but I believe I might be switching over from 2D backgrounds to 3D backgrounds. I have a lot of experience in 3D and if I can successfully make my 3D backgrounds look 2D then I might do all the scenes in 3D with 2D sprites for complex objects like trees, bushes, skeletons(Halloween decorations), etc.

Tell me what you guys think. Should I stick to 2D backgrounds or should I go all out with 3D or combine the two?
