Detri, if you didn't use all the content you'd planned to, maybe what's done is just the shortest version of it.
The fact that it seems complete at a very low word count doesn't mean you cannot or should not revisit those notes and attempt a longer, more publishing-friendly version using the same concept and characters. It's not unusual to write the same short story many times, cobbling together the final version from what's best about every other version.
You have enough posts here to put it up at SYW to see if people feel this version is complete and sufficient in and of itself. (I know--scary!)
Maryn, noting it's a double-spaced page
