This is the only time, iirc, that I could choose just 1: That is, #4 by Ivan Kramskoy. I think it’s because He has a look on His face that we’ve all known a time or three in our lives and so can identify with it. (Much, much worse in His case, of course and however.) That is in addition to the grand beauty of the painting itself.
Nicely reasoned and expressed, Claire.
