wha! 208 mb? yikes... I didn't realize there were brushes made specifically for creating renders. Or am I seeing this all wrong?
I tink he means sigs. You can make your own brushes. Check out hte tutorial section. There should be a brush making tut in there somewhere.....
uh...creating or editing...? there are some anime brushes that have more or less a usable render...it just gives the basic shape in the foreground color
