Hi PuddingNL,
allow me then to be the first

I just saw this picture now and I like it.
The composition is good and the background left side offer some perspective. The plumes of steam makes the image a little less static. It's certainly a beautiful engine.
Since I'm looking at a thumbnail of the image, there are probably some subtleties that I am missing. I do see a little bit of haloing and generally my personal tastes do not lean towards HDR..or rather HDr that shows as HDR, just share some preconceived bias I have.
I find myself wondering if it the image would have been more "imposing" if you had dipped the perspective a little..e.g. taken it from a lower angle perhaps.
Thanks for sharing
Cheers!
