I should add that the image I posted of the library at Anderson, although nominally a three image stitch, is actually around twenty-four or so image total being blended - first for exposure and then for stitch. There were probably eight images per that I blended manually, never liking any of the automatic routines that various software solutions have. Personally I like a more natural look, but that's just me. The basic blend and stitch took about half an hour, then a couple more hours fine tuning. This is actually not even the final, but it's what I had on my laptop.
As far as the original poster's HDR is concerned, I think that for some applications it's probably fine - where you want to create a particular mood or tell a certain story, like in a CD or book cover or magazine editorial, but for general architecture, it's something that might not wear over time, but if the client likes it, go for it.
