I think you have done a great interpretation. As a former painter, what I see missing is the parts that make it look 3D. A painter calls it shadows. For instance, on the stone wall, if you had a slim white strip on top it would give the fence more demention. The top would be lighter because it would be in the sun more. Pm me if you want more info. It really is pretty. I hope you know this is constructive criticism.
