Excellent initiative!
I write a lot of flash fiction and short stories in many different genres. I'm always eager to improve on my craft and try different avenues of writing. I have written quite a bit of sci-fi and I would say I focus on character driven stories.
I feel as though my craft is steadily improving so perhaps the latest is greatest but a story I'm proud of I posted a few months ago is this sci-fi one:

If you're not in the mood for sci-fi and more for literary/thriller, this entry won second place in a writing contest recently: https://steemit.com/fiction/@cizzo/a-stabbing-in-new-york
