It's a good start but try adding more life to it: birds, bugs, bees, butterflies. There is something wrong with the horizon, you can see where the sky meets the blue ground (no ground). I'm not sure but is there a piece of wood in the middle of the image with barb wire around it? I suppose that the mill should look old so I would suggest adding details like things hanging down from it and making the wooden pieces a bit askew.
