First “theme” I’ve ever made, did it more to test if I figured out how. It works, but I can and will do much better on future ones. This is just dark ocean water for dock, and badges are square pictures of a setting sun with small typewriter font inside.  Made several icons for the settings app, but none on home screen yet.  11 compatible for all devices, tested 9.3.3, 10.0.1, 11.1.2 and 11.3.1.

Dock image doesn’t show up if you use FloatingDock
