Good shot Chris, I like the pose and the setting. I appreciate very directional light but I would suggest at the raw stage decreasing contrast by 1 if you use DPP I would also lower the highlights a tad and lift the shadows, if you already did that I would lift the shadows a little more in Photoshop and decrease the brightest highlights a little.
The details on the breast look a bit coarse to me, perhaps a bit more sharpening. I do agree with Jon about lightening the shadows a bit, as some of the blacks under the bill are blocked.
