they look much much better with a good shader setup, and even though I personally do not agree with your statement I personally am starting to think I could do more besides mostly rounded rocks.
also, its rather easy to just say “lots more work” If you think so, then provide insight on how to improve the rocks.

Don’t worry, they wont cost more than i.e. a few burgers or salads would cost you
