This is nice, great subject and composition.
I think it is nice is colour but the big problem with colour is the people in blue. They may be nice people are a bit distracting and mood deflating.
Maybe b&w would lessen their effect, but I do like the greens and reds in this one.
Nice train with great steam.
I personally don’t like white sky in colour photos and would crop as much as possible.
B&W could be interesting photo as well.
