@adrian2301 This is my favorite result so far:

I know the video shows a fully procedural texture setup, beginning with a gradient texture like your’s truly. But what if you hand-painted a black-n-white texture that roughly matches the shape of the clouds in the art? Then you could add the breakup textures to get the final poofy effect. Since you can adjust the UV coordinates just like any other coordinate, this could be a good way to fine tune the shape while not losing all the procedural breakup.
