Your world building is phenomenal I can tell you put a lot of thought into it. I don't know why you stopped writing, if its because you are stuck. May I suggest going back to the beginning reread your notes. Remember the original idea or just read the story again. I have never finished writing a book but if I want to pick it up again after a long break that's usually what helps me. As a reader I believe your work is good enough to publish. But if your only doing this for fun then remember the joy.😝🤣🙃
