Is there a way to detail the images drawn with the brush tool?

Question

Adobe Illustrator

I know several ways of coloring and I don't like any of them. Can someone tell me their way of coloring objects drawn with a brush? Thank you.
As far as I understand, it is necessary to always close the outlines, so that later it will be easy to paint, right?

Answer 1

We paint with a brush, do not leave open contours that we would like to fill. Once drawn, do Object- Expand appearance - expand - path - clear path. We pour and rejoice.
