When you consider an approach such as "soft focus", the way you should think about it is photographically. Does my "soft focus" technique contribute to the overall photo, in what way, and will the viewer see it as positive?
The general guideline is that the centre of interest should always be sharp and in focus. The problem with this shot is that most viewers: pro, enthusiast, and otherwise see it as having no centre of interest. I know from getting a lot of similar feedback at all levels from similar shots.
