JellyS2,
Congratulations on getting so far in writing.
First thing you need to ask yourself is this:
Does the story feel complete?
If you're interested in having someone comb over it then I'd suggest a Beta Reader. (This thread
here has a list of BR's that have offered their services)
If you don't want someone to read through it then your next step would be to either post it or submit it to archives.
