Neopatogen Sketchbook

I think I recognize CSP's tapered pen and textured pen in some parts, but you probably tweaked the brush settings a bit. I found out that these brushes can also be interesting for semi-flat coloring (if that makes sense).

If you're interested in surface tension effects, MyPaint has some pens that "drool" ink in proximity to other lines. I'd need to find them back, I'm on a broad software/brush exploration right now.
