I do not know enough about HDR, myself, to truly give you a proper critique on how you have/have not managed to execute your conversion to HDR. So you will just have to make do with what I can say. And that is that this piece of gorgeous in its ability to be both melancholic and yet invitingly beautiful.

There is something welcoming about the lived-in quality of this building, and yet something somehow sad, forgotten, and neglected that is communicated through the graffiti and the lighting of the piece. It's as if only those of us that can step outside the photo can truly appreciate the beauty of this architecture and landscape.

Again, I don't know much about HDR yet, but to me this is perfect. I cannot tell where one exposure begins and the next ends; and that is a sure sign that the merge is flawless (at least, in my eyes). Meanwhile, BNW is absolutely perfect for this shot; as color might actually take something away from its emotive qualities.

The only criticism that I have to offer is purely a personal quirk: I would have cropped the partial street light out of the right hand side of the image (or shot the exposures to include all of it). But that's just a weird quirk of my own, and in no way affects the overall impact of the piece.

That being said, it's not the most original image, no. Probably not going to win you a Nobel Prize in Photography. But I think it's still a perfectly impactful and lovely visual piece. Overall, this is definitely a great example of miminalist HDR work.
