Tree Work In Progress

I walk and drive passing the trees along the road side near my home everyday. The trees have small white blossom during late March and middle of April. They don't look very splendid like cherries. But it is very freshing and calming. I like the white, green and a light fragrance coming from the tree. 

I want to paint the trees with green, white and a bit yellow. Although I don't see the yellow in the tree, I feel the yellow is the color of the gentle scent. The above is the sketch. I am constantly visualizing in my head how the tree should turn out to be. I will work on it as soon as I got some time.
