By no means a defnitive list, but a great start. What are your thoughts?

Read more of the stories, to get more reviews on your own stories.
The more you help other people by reading their stories, the more they’re inclined to help you by reading yours. Feedback is at the heart of Twisted50.

Engage in conversation.
When you get feedback, respond to it and ask for clarification for points that you agree with and disagree with, so that you can further understand how your story is landing with readers. You may also make new writer friends!

Strengthen your premise.
Zero in on the spine of your story, the beating heart, and figure out how to make it more original, possibly more shocking, harrowing, and horrifying. I would always argue for making it more melancholic too. Horror has an inherent tragedy and sadness inside it.

Start later in the story.
Consider jumping into your story a paragraph or three later to elevate the pace. You may be surprised. Consider opening on the ending to, then jumping back in time. See what happens. Unless you have a clever twist, we can most likely predict an ending, so the journey to the end is what matters most. Take people deeper at the start so the journey is inherently deeper and darker.

Make the opening deliciously twisted.
The very first sentence should be evocative, terrifying and grab the audience by the throat. It should let them know they are about to be dragged into hell (which of course they want). Use deliciously twisted language that makes us all shudder and shiver.

Turn a phrase.
Revisit your common turns of phrase and elevate them, reinvent them, re-imagine them, even make them quirkier. Ask others to point out where you may be using ‘vanilla’ turns of phrase.

Reduce, refine, reduce, refine.
Every story that has ever been sent to us has needed some editing. Read it through and get aggressive with the editing. Make it shorter. It will read better.

Find the trope below the cliché and re-imagine.
Understand the tropes in your story and then, if you have any clichés expressing these tropes, re-imagine the clichés in new and unique ways. Nothing wrong with a functionally cliché in draft one, but re-imagine it for draft 2.

Spellos, grammar, and punctuation.
Re-read your story, put it through spell checkers, and tools like Grammarly. Correct any and all errors you find.

Don’t resubmit too early.

Utilize the value of having your story read by as many people as possible and engage with the conversation BEFORE sending in draft 2. Remember, once you send in draft2, there’s no impetus to continue to leave feedback. As you submission is now locked.
