|Hello, J Sheehy. I'm HWinB.C. I found your story on the plug page I enjoyed reading it.
Note: I am not a professional editor or expert with English and Composition but I have learned a few things along the way and hope you find this feedback useful.
Overall Impression: It was indicated that the story is a flash fiction for the Twisted Tales Contest, so I was looking for a twist. In your plug you had said a story of love and revenge, so the set up was there.
Your use of descriptions is wonderful of nature. You truly delivered that Genre in full. Well done. The story left me with a lot of questions. What was the act of revenge? Did someone get killed? From Who or what was Dave set free?
Plot: Your plot starts with scenic nature moving into the story of a betrayed marriage and into a boat accident. A twisted act of revenge for betrayal. The plot seemed to have been delivered in the middle of the story. I understand there are limitations on 300 word contest and it takes a wee bit of magic to pull the big picture into a little one. I appreciated what you have accomplished.
Style and Voices: The style and voice stay consistent as a narrative of the main character.
Scene/Setting: The scene and setting are excellent. A lakeside getaway encompassing the reader completely into the sparking water, nature sounds, crackling trees. A poetic description of all of it. The setting for a "boat accident" with her husband Dave fishing is well done.
Characters: The characters are well developed of the woman scorned by betrayal, a husband who believes a fishing trip will fix everything, and the mysterious Bill.
Dialog: The main character provides all dialog internally. The internal dialog is used well for the telling of the story.
Grammar and Mechanics: I didn't notice any glaring grammar or mechanics issues.
Suggestions: As the reader, I would like to know what the act of revenge was and if someone died? She couldn't see Dave, then she saw Dave on the other side of the lake with the fish, then Dave was going to have beers and talk over old times with Bill (the mystery fellow). It was confusing.
Thank you for sharing your story. Keep on Writing!
