Yes, I like the look of your first hdr attempt, Patrick.
It's good because it doesn't show the tell tale signs of overkill that many hdr shots have such as over doing the black elements. Well done +V
This is my first HDR attempt. Since it was a gray day I went to this spot where I knew the "tunnel" would be less well lit than the wall. I used three images to merge, one for the wall, one for the window area and one for the door. This is just a straight merge with using any adjustments, I wanted to see how a basic merged image would look. I like how it looks.
