Interesting shot - nice use of HDR in this one. Agree on the suggestions of a crop off the lhs, maybe as far as taking the first fence post out? I'd also experiment with taking some of the foreground out with a crop off the bottom - perhaps up as far as the top of that first post.
It's all a matter of personal preference really - I get drawn towards pano crops with landscapes, others don't. Well done on making the effort to get a shot others (including myself) probably wouldn't even try to get
As an aside, I'm really liking some of the work that's being done in HDR on this site lately. Unlike some of the earlier work we saw (where there was a tendancy to push every extreme possible), I think there's a move to more subtlety in the images.
