Just to let you know i very rarely go with the rules of thirds crap , i don't even care for it when looking at other peoples photo's. It's just a rule that every tom dick and harry has copied and made it the acceptable thing. I've had many arguments in the past on other forums with the rules of third , so that crit is out the window
It's on level , i always as i repeat myself use the " straighten tool ".
I would agree with you that its not quite centered however when i took the shot is how i was walking down the path to the church.
