Love the personal sketches. I aging they're drawn digitally? If so, how do you get the "real ink" look

I use Manga Studio, which has very authentic-looking brushes, and I make sure to turn OFF the auto-correct feature (which smooths out any variation in the line work). Recently I’ve been deliberately drawing scratchier and rougher to look more like real pen work. I also have some custom brushes I made from scanning in dry brush strokes.
