Tunnel of Trees More Vegetation

I am tying to keep this painting bright and cheerful with light coming thru between trees. When there is no bright sun in the area, it can get pretty dark on this road and not that interesting to paint or look at. The trees will go a little darker in the end. Sunshine is coming thru the trees on the left side. I have masked the center lines on the road so we know it is a road and not a walking path.
