I like the idea and composition, but the blurriness and grainyness combined really don't do it for me. I think that soft focus alone, or some fine grain applied could be good but this just looks like it came from a camera phone or something.
Mike is a hat expert and loved the cowboy hat having recently visited a spred last week. Celine loves baseball caps. I though the image was a bit blured
This is very out of focus and has what looks to be compression artifacts in it. Too bad for such an original concept. Consider shooting closer to your subject.
