What was used to do this? What brush should I use in Sketchbook?
>m-muh the brush doesn't matter what you need is knowledge
I just want to know what he used to do it, because I don't know any brushes I could use to achieve that effect

Looks like watercolour over graphite to me. Could be done with a round brush or maybe a flat in some places
Looks like gouache to me, maybe over a charcoal or pastel sketch. I'm sure google could serve you better than waiting to be spoonfed on 4chan.
