Nice. The resulting graphics style reminds me of a Short Hike, which is a family friendly bite sized 3D adventure and exploration game. I'm not affiliated in any way, just enjoyed the game with my kid. It has a nice balance of story, challenges, and some platformer action. https://ashorthike.com/
Edit: IIRC the shader a Short Hike used was discussed in the GDC talk by the game's author: https://www.youtube.com/watch?v=ZW8gWgpptI8
