Ahhh thank you! <3 For my recent pieces, it has been the following two from CSP:

1923330 (Mostly Pencil RS) → For sketch/lineart/flat colors

CSP Default Gouche brush → For painting/rendering

I have a few pen brushes I also use for smaller details and random moments but I think those two above are the ones I use the most lately o7

If you also wanna know how I get the grainy effect in most of my works, I just slap on a perlin noise layer and put it in soft light while also lowering the opacity to 20-30%! :0
