Michael on Tractor

This is a painting of my grandson done from a photo taken while on his favorite tractor at Wagner Farms in Glenview, IL.   I considered this painting finished a couple of months ago..but something was not quite right, the background was too green and dark...I added more purples and lighter greens and lightened the sky, so that the background colors would not compete with the strong colors of the subject.   Will see if I still agree with this down the road...This is one of those paintings that I am struggling with due my tendency to paint what I see on the photo...practice makes almost perfect.....
