Hi, Diane - and first, let me add my welcome to Moira's. I hope that you both enjoy the site (and the Critique Gallery), and find useful tips and good ideas here.
This breaks down into four areas for me. First, the taking, followed by composition, technical issues, and processing.
It's a brilliantly seen shot, whether it's a setup or a grab shot. There's a real air of a saloon girl in a Western film, maybe on her way to ruin the sheriff's wedding. Or, maybe, a girl out on a hen night (I'm not sure about the States, but here in England a hen night can begin any time after daybreak!)
I'm interested in how you came to take it, because the situation does affect how I view it, and it will be the same for most other people.
Composition is excellent, with the elements of the picture arranged around the frame in a way that helps tell the story.
Technically, all the settings are OK, although they aren't the optimal ones for the situation: I'd go for aperture priority, not action mode, and 100 or 200 ISO, plus manual white balance. That isn't to say that your settings are wrong - just that they suggest you haven't completely taken control of the camera's adjustments, which means that there is a slight risk that it chooses something that actually doesn't work well.
And, as Moira says, it's the processing that strikes the eye. It looks like some sort of off-the-shelf mod, the kind that 'phone apps do. These are fun, but they don't always work well for more serious applications, where some of the side-effects (like the halo around the church) can really get in the way of the viewer's appreciation, like marks and dust on a car windscreen spoiling the view. So I also encourage you to upload the original, so we can see it without the processing.
An alternative view (using another of those special effects that I am wary of, so it may be a little hypocritical!) is in faded monochrome - like an old photograph, found in a dusty attic. Photography and the Wild West did overlap, at least in terms of dates - I'm not aware of any great quantity of pictures having been taken, though...
