Very nice, I was in Venice a few years back and this brings back memories, I think if you cropped out the bridge and light coloured buildings on left the section remaining is a really beautiful scene in its own right – a real study. It does look like an oil painting with the different textures and colours. Well done.
That looks great in the large version-
loads of detail, even in the large dark area in the centre-
The two lit areas have slightly different colour temperatures,
with the lighting under the bridge being slightly cooler or greener-
I wonder would it be worth trying to balance the colours a little better?
