I think you've done a pretty good self-assessment on your photos - I don't have too much more to add than what you've already mentioned. I find that first one really interesting actually - you've taken it on an angle which adds a good perspective and ensures there's depth to the photo. There's a pole on the right thought that I think if removed would make the capture look better but I'm not sure if that's possible with the perspective you've taken. That pole also gives me the impression the photo needs a counter clockwise rotation because it's quite prominent and close to the right edge of the frame.
