Help editing photo in Lightroom

My fiance and I recently had engagement pictures taken. Trying to be a good person, my fiance allowed her cousin to take the pictures to build up her portfolio. Well when it came time to edit pictures she gave up because it was "too hard" so now the responsibility has fallen on me. I'm a graphic designer but I don't have much experience in Lightroom. I've downloaded some presets but I'm hoping someone can give me some tips on this particular photo. There's just a lot going on in the background for my liking. Can this picture be saved?? Thanks!
