I'm stuck between a rock and a hard place

So for all you authors out there, I have a question for you. If you have a story that you've been working on for a while but are not sure whether or not it'll be worth releasing, would you release it and hope it sticks? Or would you just can the story and maybe come back to it? I'm asking this because I kinda wrote a story that was inspired by a few different stories that I've read, but I don't think I did it in the right manner to warrant releasing it. Reading back on it myself It seems like I screwed something up in one way or another but I'm not sure. Have any of you ever had to deal with this? I'm just stuck on what I should do with this particular story.
