A bit late to the game for
@The Scribbling Man, but I would echo what the others have said about your entry seeming more a scene, than a story. But the writing was some of my favorite in that Challenge - I thought it was very well written. My only other caveat was that I wasn't 100% whether it hit the genre or not - I went back and forth on that. But it's got great atmosphere, and it's one of those where I'd like to know more (you mentioned it was part of a longer work; the genre I'm sure is clearer in the longer piece).
And
@therapist, I really enjoyed your story, too! A good, fun title started things off, and was followed by an interesting story that packed a lot into 75 words. I think the only failing was genre; I bet this would have received listings if it hit the genre bullseye (I would have listed it), and perhaps even some votes. One quick, small thing about the intro:
The wasp flailed, struggling to escape the water. Rolling waves—from the swimmer—battered the wasp against the pool’s edge as it fought for purchase...
I think 'wasp' may have been repeated a bit early here. Maybe the second usage could have been replaced with 'creature' or insect'. Small thing, though.
I would say really well done, both of you, as I believe these were each of your first Challenge entries. Don't be discouraged, hit the genre a bit harder... try to make sure you've got the theme in there, too, and keep up the good writing, CC
