Just thought I'd let you know this is a contradiction in terms. Vector does not involve brushes. Brushes are raster tools. Vector is completely the opposite.
Thats what I thought, if you look at one of Irrel's tuts, he shows a cool vector thing you can make. Its mainly just the circle tool, rectangle tool and all that stuff together to make some kind of object. I am horrible at vector art though unfortunately.
thank you for mentioning it. and btw, its possible to vector with brushes. its just so hard that i'll never do it again
You might also want to look for retro brushes, because they usually look similar, and both can be used for the same things.
