At worst that may be a soft lens. The skin tones are over-saturated. Softness is most apparent around his tie and where her dress meets skin. Given that you've named the image "HEeditsharper" though, I take it that you've already tried sharpening these.
At f/6.3 and 85mm though, you have around 0.5m of acceptable sharpness at a focus distance of 3m (which I'm guessing is about where you were, given the size of their heads in the frame) to work with in the DoF, assuming you shot this with the EF-S 55-250.
If these were retouched, you've gone too far. But then I don't think they have been because of the lines under her eyes—if I were retouching these images that's one on the first things I'd tone down, with either the clone tool or a curves adjustment layer and layer mask to tone down the local contrast (or both), and some gaussian blur (which I'd apply to all the skin) with a layer mask, brushing it in with a very low opacity brush.
Furthermore, on the technical side, these images have the camera's RGB profile embedded (whatever the heck that means), and not sRGB. That may account for the colour balance issues. I noticed that when viewing these on my desktop via OS X's quick look, the red channel became WAY oversaturated.
I'd try to take these and fix the colour profile myself in Photoshop to provide an example, but my computer is out-of-commission for any heavy editing work for now (no fans

).
