The subject of the current series of paintings is trees. The first painting is an abstract of the white birch tree. They have have such distinctive trunks, with the colors of the bark and the lines being horizontal instead of vertical like most trees.
The blue in the painting represents water since these trees like to grow in areas with a lot of moisture. The green in the painting represents leaves and grass and other green vegetation in the area.
