It will be easier to provide meaningful feedback if you can provide reference images that you are working from (you are working from reference, right?).
There are a million different types of rocks, what sort are these supposed to be? Without knowing that it's difficult to say whether you're anywhere close.
Just to add to it, I tried sculpting out a smaller rock first with the same reference, and I am wondering how to tell if it is a good bake or not just on the normal map so far. (I tend to have issues telling what's good or bad with the exception of the obvious errors.)
