I used Marie's Chinese Watercolor paint for this. This is not a Western watercolor piece.
Chinese watercolor paint have different properties from Western watercolor, and a lot of Westerners give Marie's a bad rating because they didn't know that they are meant to be different.
I personally really like Marie's watercolor and Marie's Chinese Watercolor.
Contrary to most beliefs, you can use Chinese watercolor paint on marker paper, comic paper, and watercolor paper.
A lot of people thought you should only use Chinese watercolor paint on rice paper, this is false.
