this a dry effect brush i made, when you push harder its opacity goes up and when you go faster it gets thinner and also the opacity goes down.
to use you just use it like any other brush you may have used with pressure sensitivity effecting the size but also the speed you draw at effects the opacity and size too. if the changes from going faster happen too soon for you you can go into brush settings and go into opacity and change the value for speed until you like it. you could also turn off peassure for opacity because that gives a fun effect too :)

hope you like it :)
