A pleasing, distinctive image that meets the challenge well.
I must begin by admitting that I have never consciously used the Orton effect myself so I am not best qualified to assess how effectively it has been used here. However, your image is the first I have had the pleasure to critique that shows the sort of distinctively different and obvious effect that I was expecting so for me it works very well indeed.
I like your composition, I like the pastel colours that are broken by the bolder colours of the man and the bench. I like the combined effect of the soft focus interspersed with the sharper details. I have to say this to me feels like a really splendid example of this technique that has been so convincingly done it is really exciting me to the extent that I want to go out and try it for myself. There must have been some tough competition in this challenge because although your very respectable score has put you in the top ten from what I have so far seen I think this really deserved a ribbon.
