I noticed a very slight tilt on the horizon, which seems to be even strengthened by the fact that the right side looks to be drawn to the bottom by the line of poles... I also think that line of poles extends a bit too much to the right, fully dominating the wide open space; I'm not sure if that was the right choice here. There is also a very stark contrast between the black poles and the rest of the scene; it doesn't seem to blend together very well. And on the cropping issue, I would consider loosing some of the space at the bottom. Here's a try to implement some of those points...
