Shameless(?) Plug-In?

I'm not exactly sure how the Feedback portal works, (or how Prose really works in general; I'm a newbie, guilty as charged), but am I allowed to advertise here? I just want some feedback on a short story I recently wrote, entitled Of Shadows Unseen. It's a bit under 3000 words.

Again, if self-advertising isn't allowed, I'm all-the-more willing to remove this post.
