Stylized Game prop/asset - Rocks with earth

I'm trying to produce more these days. After I started playing "Kena, Bridge of Spirits", I want to produce a quick study of stylized low poly game assets.

Making stones is one of the hardest things to do it for me, for that i used Zbrush to deform some spheres and once with some diferent proportions i used Flatten/Trim dynamic brushes to give smooth/flatten angled surfaces. To texture, used baked system and Substance Painter to give some detais.
