Emily,
These are some great glimpes into very intriguing fantasy worlds. Now...more?
I know you said that these are flash fiction, but in everything I've heard about flash fiction, it's still supposed to have a plot. Granted, in the ones I've read, the plots have been...um...weird/hidden/strange/odd/absolutly insane... But I don't know that these really fit into the flash category. Great imagery, great word pictures, but not a 'story,' per se. You know what I mean?
Maybe 'prose poem'? (I know, it seems like a contradiction in terms, but I've heard of them.)
On the other hand, should you choose to put them into a longer story, I certainly won't complain.
