I love the look of the dog in this, but it didn't pop for me until I began experimenting with some of the stronger details enhancement settings in Topaz Adjust. This is way more processing than is my custom, but I think this captures my vision pretty well: The details enhancement on Bowser brings him or her to life --s/he seems to leap off the page. Meanwhile the crowd has acquired a sort of Norman Rockwell litho quality, while the background trees have become a bit abstract.
I didn't like the woman's face with the details enhancement -- it was not pretty and she deserves better -- so it's masked out and her face remains more natural. I've also dodged the background just a little. I hope your attention is drawn first to the dog, second to her face, and third to the sea of community members in which they swim.
