If it happens, it happens, but with this brush the line weight is best added in manually by going over your lines repeatedly until they’re thicker (or lessened via trimming the edges of the lines with a low opacity, soft edge eraser brush).
Don’t worry too much about line weight via pressure**.It’s pretty simple - no special textures or anything other than the settings you see.
I was trying to find a brush i felt emulated manga lines and i couldn’t find anything so i screwed around and did my own.
