Corny tracks

This is a cornfield just outside of Leyburn, North Yorkshire. This was processed using Photomatix using 3 exposures on a Canon 650D at f/14. I'm just playing about with Photomatix so any comments, critiques or opinions are welcome. There's another similar image I've posted, which I processed using Lightroom - again, I'm only experimenting at the moment. Thanks.
