Thank you @RedLenai for your help, but I'm a little confused on the short line technique. Do you that each stroke is actually a short, quick line that you later go over to darken it or connect it to another short line, like feathering the line rather than in one stroke?
I'm having a bit of an issue with finding an "ink discharge" brush in Krita, could you recommend one, if you know of a brush that could get a similar effect?
Also, what specific setting do you believe the brush has? The opacity is still dark but slightly different, which I'm having a hard time recreating.
Thank you for your time and help.
