firstly im going to say that i love this image!! im a great lover of hdr in all its forms and this on stands out!
ill also say though that good HDR doesnt need to conform to normal so-called rules of photgraphy (comp, lighting etc) hdr in itself can hide a multitude of photographic sins (which is why i use it alot lol). if anyones going to critique an HDR image in a way they might critique a "main stream" image is futile. HDR is a style in its own right - you either love it or hate it! personally, when done well, like this image is _ I LOVE IT!
