Here is my first attempt at a planet using your shaders. I'm making a kind of avengers in space game, so I wanted something with a more pen & ink style than pixel art. It looks like the shader scaled. I had to change it pretty dramatically, but I learned alot reverse engineering it.
I added those polar ice caps, modeled on your shaders, but using textures rathe than in shader noise generation.
