You can get rid of the following nodes:

Elevation gradient (and its profile gradient) - Reason: not doing anything.
Invert: can be done using the stone noise alone by making the "noise" color black and background white. You can also hit the invert checkbox on the impulse node and it'll just invert the colors right there on the spot. Now you can safely remove the invert node!

A couple notes to keep in mind: your filters kinda have jaggy edges despite having high anti-alias counts. In the case with this filter you got the "minimum" node doing much of the damage here. You can enable "anti-alias" in minimum, but it typically leads to ugly edges regardless and it also renders slower due to the extra computation. Components such as Minimum, Maximum, Median, Percentile, smudge kinda do funny things with crisp edges. I'd be warned.

You should also just replace any old component with the new one. It's just a version thing, there's absolutely no 100% need to do it, but it just looks healthier. lol

Cheers.
