Linux bros, I'm looking for good Photoshop-like brushes for Krita so I can follow along with the 'Med's Map' course.

I've tried to import the .abr file into Krita but it only imports brush tips which sucks since it doesn't contain the intended effects of the actual Photoshop brushes themselves.

Any brushes or tutorials on how to use Krita effectively in this manner would be good too.
