How to get Yizheng Ke's textured stroke style in krita?

I would suggest trying @RamonM’s presets, here:

INK brushes for INKTOBER 2023. Feedback.and final release - Resources / Brushes and Bundles - Krita Artists

(Edit) - In terms of how to achieve that type of breaking stroke, it would be a combination of tweaking the main brush tip, adding a masked brush (as provided with in Pixel Engine), adding a Pattern for texture, etc.
