The Feedback Forum is to seek responses to material that has been submitted to the site editor and published, not for un-vetted new material. I suggest you expand it to at least 750 words and submit properly. You can then start a thread with a link to your published story.
This rule is in place to ensure that no material that contravenes site policy with regard to content gets posted. Your excerpt doesn't contravene any of the content rules, but it could have.
