Hmm.
Well, I think the third picture might be a silk purse anyway. It needs a bit of work on it, but I can see real potential there . . . .
I'm not keen on the polaroid treatment, and I think that the second one could be fine. But the third one intrigues me.
More drama in the sky (which is dramatic anyway), more colour in the graffiti, and more concentration on the lines . . . . but none of this requires anything more than ordinary pp.
Personally, I'm a firm believer that it isn't worth trying to rescue a mistake (unless it's of the bride). I'm also uncomfortable about any post processing which wasn't 'envisaged' when you took the shot, and packaged effects always set my teeth on edge.
Still, I've looked again at that last shot - I think it's worth a little more work.
