The only thing that bothers me with this piece is the background. It takes away the focus on the machine (which btw is amazing on this photo!!!). There's also this hard transition with the blur on the left side at the wagon that's furthest away. It's like a straight line between blurred part and part that's focused. What i would do (mind that this is only my view on the piece) is to tone down the brightness on the background and also tone down the HDR on it (there's no need for it on the background in my opinion). I would go for the effect of people guessing if this is HDR or not . The composition is amazing (though there's a piece missing from the headlight i think) and that is something i wouldn't change . Maybe tone down some of the highlights as well cause they are burning at the moment. I like the whole idea and appreciate the effort put in this. I'm in no way trying to look down on your work, just wanted to give you some constructive criticism
PS: I love these old trains This photo gave me a smile on this shitty day
Thank you for the constructive dealing with the picture. There are some suggestions which I agree with. The picture is some years old. In the meanwhile I changed and improved some techniques in photography and prozessing procedures. You can compare this with my newer pictures.
