One of my favorite type of newspaper assignments is to capture "wild art", which is defined as "Stand-Alone, Feature Shot, Enterprise art are found moments that are intended to be realistic slices of everyday life" (definition taken from this glossary). These are typically images that caption themselves, not needing a lot of words to get their point across. For this challenge, I'm scoring images as whether I'd like to see them on the front page of a paper as feel good wild art. If I don't think they would make the paper, I'm then asking myself, "does it make me feel good?" If it doesn't do much for me, well then, oh well...
This looks like a great opportunity missed. All the elements for some "feel good fun in the sun" are there, but not as photographed. Maybe if there had been interaction between the two, or if you had focused in on one or the other. As is, it's more of a seaside snapshot than a strong image. Just my personal opinion, though.
