I am always changing and customizing my brushes during the work depending on the result what I would like to achieve (I even creating some brand new brushes for most my illustrations hahah...). The set contains about 60% of collected brushes from all sort of digital artists from the web and about 40% of my custom created and modified brushes.
You can find the brush set at the sidebar under Downloads from know on and download the original version of the swatches I use from Sketchling at CGHub > HERE < .
Hope you can use at least some of them! :)
