Natalie's collection of ultra-short stories (I think the term is flash fiction) are an intriguing collection of ideas and characters. Natalie's style flows well, although the narrative voice varies a little between tales (I imagine as a product of this being a set of assignments). There are some great ideas here, but I think some have been lost in the flash fiction style with the urgency to wrap up the story in occasionally abrupt fashion evident. There are definitely some that would benefit from expansion towards even just 2000 words and that may be worth considering.
There are a few typos to adress but they don't detract from the stories at all. Look forward to more of your work on CN.
