Pano - Farmland Landscape

Well while visiting me grandparents I had the opportunity to take this series of shots. I only had a roughly 2-3 minutes as we were driving through, and my gear was in the back so this is taken with the 80-200, as a result this is actually 25 shots stitched together. Anyways the family that live up this was (Halidays Point) really liked the shot, but I though I might as well upload one here for your comments and critique.
I think my PP may have done a little astray as the shot seems a lot darker then it did originally... but on a uncalibrated LCD it's hard to tell, any feedback on the exposure/brightness would be welcomed!
Here it is.
