Looks okay to me, apart from one tiny thing; can you actually see the difference between a Detail size of 16 and a Detail size of 2 or 3 in this set-up? (Top left Noise Texture!), especially since you mix it in at only about 20%…
Just asking, because usually the difference between a Detail of 2 or 3 and of 16 is hardly noticeable, but 16 is a LOT more computational expensive…(Detail is the most expesive setting in the Noise Texture!)
People do this a lot: just sliding the Detail up to max…’more is better’…Well, I’ve got an old computer, so I have to be careful 😉
If it works here for you that’s great, just be aware of this, in case you get more complex node set-ups 😉
