Books are like art they aren't for everyone only a select few will like the book. It's not you that didn't do right, and words are a weapon that hurt more then a sword for they cut deeper, but just know that what was said isn't true, sure theirs room for improvement but give one situation that's does not have room. Everyone has room for improvement even advanced writers make mistake and have areas that need improvement there are many published books out there with grammatical errors along with spelling. It's just a test life throws at us sometimes to teach us who we are and what we do with these situations. I got kinda carried away but the point I'm trying to make is that: your a good writer you have potential and that will only grow with practice and isn't that what this website/app is for?
