On the contrary - I find that the way you drew the fissures and irregularities was correct and appealing. Change nothing ! And I agree details are fun indeed.
The question is the amount of detail and there is no precise answer on it - it depends on style and taste.
Once you did correctly your valleys, ridges and peaks and connected them, you start shading and adding details.
Shading is easy.
Details are subjective.
Too little and your picture lacks life. Too many and your picture looks cluttered.

The way I do details is asking myself at every detail whether I add something valuable/significant to the overall look or not. Once I feel that the answer is not, I stop.
But this is only my way, others may have other ways. I do not think that it is very important anyway.
