Btw, welcome to BotB!
Also: that is a rad avatar, how did you make/get that?

Thank you!! It’s been really fun :-)
I made the avatar in aseprite— setup the position of the planet, then painted some fuzzy blobs and animated them for a few frames (ensuring continuity with the onion skin view). Once the animation was working more or less as a loop, just selected the inverse of the planet and chopped off the messy edge of the painted blobs. Then added some dithered shading on top of everything to add dimensionality and crunchy pattern interaction between the layers.

great avatar!
