I guess my first question is, "What did you envision in your mind's eye when you composed the shot in your cameras viewfinder? I don't know how far you were from your subject but you were shooting with a longer than normal focal length but probably at wide-open for that setting. It is difficult to see where you focused but I suspect it was somewhere on the right-most light fixture. Depth of field was very minimal at this setting so very little remained in focus. Recall that depth of field extends forward 1/3 and back or away from the point of focus 2/3. However at wide open you would not have any significant depth of field anyway. Try moving away a bit and don't fill the frame of your viewfinder.
