It's tough to evaluate flash pieces. By definition, they're far too short to do most of the things that a traditional story does: plot, character, etc. I've found that the flash fiction I've enjoyed most paints a very vivid picture for you, and gives you just enough information to let you sort out the "before" and "after" on your own.
I think the writing was solid: very vivid imagery, and an interesting POV. Sadly, I just couldn't get a handle on the "before," and there doesn't seem to be an "after."
