So body painting. Important things to remember. Best practices. What's the main focus?

Here is one of my body meshes. I'm using one of the zbrush materials with a peachy skin color, and I just filled in all the dips with a very soft dark red brush. Of course it looks good through zBrush Glasses, but will it translate elsewhere? Since the skin color comes from the material my texture is really just white with some dark red blurry lines. My usecase is going to be characters with variable skin tones using the color channel on the material. So hopefully it just works.
But I feel like there should be more to it, but maybe there isn't and simpler is better
