I have an interest on candid Photos so it was great that you have mentioned them.
This one on the cover (which is in fact bigger than it appears here) was taken in Paris near the Eiffel Tower. Now a days we live in the "selfie world", so I find people's expressions while taking selfies a great motive.
This is another example also from Paris (September 2016).
I guess I could improve using your tips which were very helpful.
