It's been a long time, my friend! I hope this review finds you well.

This is a great essay, full of really useful information for those looking to improve their flash fiction. All of the suggestions were great, but I particularly liked the advice to let the story imply the events, and to think outside the box. Both have been critical to my success with flash fiction as well, and you articulated the concepts perfectly.

I think it's important that you provided the context about the Daily Flash Fiction Challenge being your primary source of knowledge, but I think you could also broaden this piece and apply the concepts to flash fiction in general (which is typically considered to be less than 1,500 words) and would recommend pointing that out in addition to your experience with a contest that has a specific 300-word limit for stories. This is an essay which is definitely equally useful for writers of 300-word to 1,500-word stories as well!

Overall, I thought this essay was excellent. You did a great job providing the reader with a ton of actionable advice about how to improve the quality of their own flash fiction, based on your own experience and success with the medium. Nice job!
