Underneath drew with watercolor pencil, Durer, on the top – Kuretake water brush. I like that is green. Pentel, Pilot and Koi water brushes transparent or bluish, Kuretake makes it in happy colors. I was a bit jealous to people from England, who can get em in colors, now got mine from London. I drew it with Zig Clean Color brushes by Kuretake, it washes like watercolor and tip is very delicate.
