Not to blow my own trumpet too blatantly, but I think this looks much better!
Although that's partly because you've also got the lichen texturing just right
- it looks really realistic. How do the render times compare?

I find this to be the case also.

Don't forget, you can relocate the object to be eroded before calling the macro.
If you move it upwards slightly it may improve things (the underside won't look
nice, but obviously that's not visible!). Another thing to try is the inner
shape - a wide rounded cylinder could well work better than the default
squashed sphere.

Looking good!
