I love books that feature connected short stories. That said, I wish I had kept notes of the characters' names from the beginning, because so many reappear much later in the book, and it took me a bit to wrap my head around who was who. Because not everyone knows everyone else. I feel like maybe I missed some tidbits that would add even more to the story--but nothing major. I can see how this could be a 5-star read for many. I wonder, if I had kept a character list, would it have been so for me?
At the same time, though, the use of the painting to connect the characters bugs me just a touch. It smacks of one of my favorite books, The Girl in Hyacinth Blue by Susan Vreeland, published in 1999. If you liked this one, I highly recommend that one. Yes it's different, but you'll see what I mean!
