The HDR itself seems fine, there's none of the usual issues associated with HDR, however the lighting is very flat, and the "glow" on the trees is rather distracting. I think it might we worth trying with a little less sky as well...
I agree with Mr. Iron. The HDR itself is decent, but honestly I don't think this kind of shot would call for HDR. Besides, I would have rather seen more of the building. It seems to have quite an interesting face
thanks for that guys. the face of the building was in almost complete shadow so i thought i'd try taking 3 shots 1-stop apart to do an HDR. The building is boarded up, i might go back at night and take some shots.
