First off - knowing that the effect was what you were after, I will not even mention that. After all, if it's worth doing, it's worth doing to excess - right?
BUT, if you want it to be the best presentation of this you still need to work on the halo issue. See, there is a very noticable halo around most of the building, and around the statue in front. Take care of that, and I think you will have a shot worth looking at.
Also, just to humor me, your total contrast is very minimal. Once you are done with the halos, try duplicating the layer and set the blend mode to "Soft Light". I am curious as to how that might look.
