It is a brush that draws fluctuations on the surface of the water.
I think it can be used when you want to draw a water surface in the middle or distance. The image was drawn with the cloud brush and the water surface brush that I put out before.
水面の揺らぎを描くブラシです。
中景や遠景の水面を描きたいとき使えると思います。画像は前に出した雲ブラシと水面ブラシで描きました。
