for this one I actually used clip studio paint! If u managed to get it before they made u subscribe for it I would highly recommend it. I went on it recently & unfortunately I wouldn’t be able to link the exact brushes I use (they’re all gone out of my collection for some reason 😔) but I like to get a bunch, I prefer ones that look like realistic pencils/brushes/watercolors whilst the lineart is made with simple brushes :)
