Inks 1

Hey looks really nice! Can u maybe explain me what the procedure was when you did this and for which parts of the picture u used the brush and for which ones u used the "pen"? Furthermore im interested in what paper and indian ink u used. Just if u got a little time to explain. Would be very kind.
And btw although I quit recently quit painting for some time youre very inspiring and I love your work.
