That is really inspiring. I posted my first attempt at HDR recently but I was really just messing with the new software. I was kinda aware of the potential with "twilight" or night photography but didnt really think that things as fantastic as this would be feasable. Thanks for this image its fantastic food for thought.
Too much HDR and sharpening for my taste - looks gritty, but it almost looks like you could touch the grit, and I know some people like that - it's personal taste. Also, too small to see the details on my monitor and screen res. - definitely couldn't use it as a wallpaper.
The colors are absolutely gorgeous, and the composition perfect. Nice job on avoiding halos too.
