This brand of storytelling is not for everyone. The author must get to the point of all those writerly devices (plot, character, story, etc.) in a hurry.
And it’s all very subjective too. Either it works or it doesn’t. And beauty is definitely in the eye of the beholder. The good news is that the investment of time it takes to read a piece of flash fiction is relatively low compared to the potential payoff of the experience.
Most of my flash fiction has been inspired by story prompts, supplied by an online community called Storypraxis. Some of the better ones are collected HERE on this website. They vary in style and substance and tone, so hopping around is encouraged.
If you’re so inclined, go have a look. Even better, take the title of the piece, or perhaps a particular phrase or character or description, and use that to write your own story. Even better than that would be to post your story in the comments section. And best of all, you could skip all this story business and just send me a check for a thousand dollars!
