Saturday Class - Wasting Paint

Frustrating day at painting class. I painted and wiped out the path at least 5 times. The reference photo showed dappled light across the path and grass. I never accomplished that effect. Below is the final painting I did after I came home and worked, reworked and reworked again.... Not a good painting. I really tried to not give up and figure this out, but sometimes you just gotta stop! The version I did while at class,  is shown in the bottom photo.
