i rotate thru them. tend to use one or two brushes for an entire drawing for sketching/inking/coloring
calligraphy section of procreate: brush pen, shale brush, streaks
sketching section: hb pencil
give concept lite: I use this the most recently (for hades fanart). I like using the jack of all trades and amazingo marker. https://georgvw.gumroad.com/l/procreate-concept-art-brushes
i haven’t used them recently (mostly used them when i was drawing orv) but i feel like i should still mention sometimes i use these watercolor brushes https://maxpacks.com/watercolor-maxpack
