The first step is to proofread the script again and again. In this way, you will be able to pick the mistakes be it grammar or sentence formation, anything. Then, allow it to be there for a day. Ask your friends/family to read the same and ask their opinion. Once your near ones have enjoyed your artistic work, definitely the world will enjoy it. You can then publish it online or convert it into a book etc. as you feel would do justice to your work.
