There are two schools. Some like the luminous look, others like the natural look.
Your photo is in the natural look area and I like it, but I find it slightly bright. I can see the detail under the building on a bright sunny day, so I would say the HDR effort worked.
I'm looking at these now with a different monitor (actually 2 others) On the current monitor the first photo looks like the right brightness and the second looks a little dark but still acceptable.
