It all depends.
You say you are new, then I believe that this is a classic "The gates of heaven have opened" and your creative mind is starting to see the light.
What I will recommend is to chase the creative flow, start your next project when you feel for it. Naturally, you will be able to do that story even better because your creativity is heading that way. When you get stuck again, with the new project, then you force yourself back to the first project to revisit it, and then you will read it with a whole new experience and eyes.
Eventually, you still need to finish one of your stories.
Good luck
