Non-map piece of art i'm attempting. My question: I have lineart done with the black brush on a parchment style background. But the lineart is too... black. I want it to look weathered and less black. I've seen something similar in the Butcher/Baker map (see reference clip). I have tried masks, then using a grunge brush to mask speckled spots out, but it doesn't look good. Anyone have any tips on how to achieve this effect?
