Just know that this reply is not in anyway meant to hurt your feelings. Do not take offence to anything I tell you. Please?
They were both decent stories, just can't say they were good. You need to do your research better for both, which might require re-writing the whole of both of them.
For Chewing Gum An Angel's Mission. I like that you're trying to write a story about music. The problem is though. Where's the music? I don't see any notes or lyrics in the story. You can't just put music from soundcloud with it and expect it to be considered a novel about music.
For Angel Warriors. You didn't correctly execute action scenes and the chapters are way too short. I was a little disappointed with it.
Now, if I gave you feedback this would be a loooong reply, sadly I don't have the time right now. I can give three suggestions.
First, actively seek out feedback from the forums, this will help you out a lot. Why? Because this is a great community and they would happily help you.
Second and this is one I myself am doing. Buy books. Mostly books on grammar and composition. I would say something about a dictionary because you spelled or used plenty of words wrong.
Third, if you don't have the money for books. There are also online guides that can help you out. In fact when you ask for feedback, some of the writers here probably have their own guides. Be sure to ask for this if you feel you can't afford the books.
Hope that helps.
