Thanks Anirban. Well, I am afraid that Lille, Roubaix, Tourcoing are less colourful than Bangalore, so as the (French ?) saying goes, you have to turn necessity into virtue... and I admit that out of all cameras I have or had, the Df does the (slightly) better job. Or maybe it is just that I learned to use proper color profiles in Lightroom (in this case, 3rd party profiles that were worth the price).
Concerning composition, I have to smile: the very dark shots were made with the camera sloppily laid on the platform, because I wanted to shoot at ISO 100 and had no tripod... on the other hand, some culling did take place.
