The best advice I can give you is that your work is always going to be different from everyone else’s. If your work was the same as someone else’s, then that wouldn’t be “creative writing," would it?
It’s called creative writing for a reason.
So don’t worry about how others will judge your work, because your work is going to be different from theirs, and you can’t judge something you don’t understand.
You also can’t judge something that’s come from the heart, because if it came from the heart, then it’s going to be beautiful.
So make sure your work comes from the heart, and don’t pay too much attention to what others say.
That’s all! c:
