The slightly blue cast to her dress was really the biggest thing I noticed, in a negative sense. I really have nothing to add to what's already been said, except:
This isn't *really* wedding photography. This is the Father of the Bride, who happens to know a thing or two about photography, seizing an opportunity for a photo on his daughter's wedding day. Had you been looking at this wedding as a chance to work on your wedding photographer skills, then sure--some fill light, think more about their pose, etc. But somehow I suspect that you might possibly have had one or two other things dominating your thoughts that day, and so I can completely understand why you just posed and shot a picture. I think you did quite well with it, really.
And, as someone else mentioned, my guess is your daughter will love this picture as much or more than the professional ones, because her dad took it.
I kinda like it more without the crop, though. Shows your daughter's wedding gown off better.
Also--your daughter looks so much like a slightly younger version of a friend of mine, it's scary! I did a double-take when I first saw it!
