I'm sure some of the pros on here could do much better, but I tried to run it through lightroom, and PS and see what I could do. Backed off the highlights a little, bumped the contrast and clarity, backed off the exposure a little, added a little sharpening and noise reduction. Then in PS I removed stuff that pulled attention away from the subjects, and added some bokeh and vignetting.
