I REALLY like that shot ... the only thing I'd suggest is that the flowers in the background atop the mirror are a little distracting being so in focus, I might play with the DOF a bit.
That is a Heartland shot!!! I wish I had a dollar for every time I wanted to shoot the same deal, but never did. The background flowers shape the mirror subject. I love how the mirror reflects a barren land. Where the background seems fertile.
