Its a nice concept and nicely executed but lacking another element to complete the composition - maybe a person, dog, cat, monkey?
There is too much space on the top also, imo, if there was a burnign sky then keep the top but at the moment its just chewing up hardworking electrons that could be better off somewhere else
So, pano crop would see an improvement from my books and the inclusion of a subject in the lefthand side of teh image, including a person just in the pergola would not be enough. Maybe having the person walking towards the pergola?
Also, lighten up that beautiful green grass, an absolute crime to have this hidden in the shadows!
