The second one is better, but I still think the sign area is unnaturally dark.
When I just got Photomatix Pro, I went crazy with HDR and tone mapping, especially tone mapping. So much so that I stopped editing the RAW but just throw it into Photomatix and see what it gives me. So much so that when I am taking a shot in conditions where I know parts of the photo will be too dark, I didn't care because I was going to try my luck with Photomatix anyways. Well, soon I realized that it became boring and meaningless and all of my photos look the same. So I stopped relying on Photomatix, but look at each photo I take and do appropriate editing, whether it's RAW editor, tone mapping etc.
When I use tone mapping or any form of editing, whatever the goal is, the underlying rule for myself is, it has to look natural..... or rather, the fact that it's tone mapped or HDR should not be the first thing on the audience's mind.
Just my 2 cents.
