Aha! Amazing!
This gets me 90% of the way there! I just need to work on getting the look exactly the way I want, but that’s just fiddly bits. Thank you so much! You’re a treasure!

I think next is mostly just trying out different noise textures, and that distortion tutorial you linked also talked about how to make it less obvious that the texture is repeating, so I will try that out, too. And of course getting the branch sway in there, but one step at a time!
