>>4472758its nice and sharpm, the symmetry in the reflection is always cool but it looks a bit off for some reason.
the river provides natural leading lines to draw your eye toward the centre of the image but your subject (the front carriage) is off to the right.
it feels very gray and the ligthing is pretty meh so come back and retry at a different time.
there is a lot of negative space in the image which some people like but i think this just isnt the picture for it.
try playing around with crop and grid lines turned on and see what different framing you can get from it, maybe different aspect ratios will help.
it wont be the best picture but it should be enlightening.
Personally, its a cool idea for a picture but like you said what you're imagining isn't what comes out when you capture the photons, keep practicing and you'll get there, i find cropping pics really helps you see framing that is already there but you couldn't see at the moment in time
