Fons /Elsa /Thomas,
Thanks for the kind words.
By way of an explanation, the bit of magenta tinge at bottom right is the remnants of another person's shirt. He was standing between me and the subject, who was in the middle of a crowd, so I isolated her as best I could by shooting wide open at 200mm. I then had to decide between posting the shot un-cropped with out-of-focus people in front and behind her, or cropping severely to get rid of the distracting elements.
I chose the latter option, which makes the composition simpler and cleaner and focuses only her beautiful features.
