I really understand one basic brush should be pretty much enough to do any masterpiece, yet I find this guide useful. I have had some hard time figuring out what settings actually have strong impact on my work, brush menu is kinda complex. Btw, I can't see transfer option up there, is it recommended to be used?
After reading this comment (just 2 minutes ago) I've decided to try making a brush or two at the most which will mimic this effect, I do not have my tablet with me atm but when I finish, I will post a link in response to your comment with a link to the brush settings in my gallery. :3
