Hey there. I like this story idea, but I feel it needs a bit of work. The plot is fine and the idea is different. But at times it is a little hard to read due to mistakes littering the chapters. I hope this doesn't get you down though because it is a fantastic idea with the way you are using the seven deadly sins. I liked the names you choose as well. Actually there are quite a few good things in each of the chapters. Perhaps you should look into a beta to read over it and fix things up and it will most likely help the story appear and sound better with a more natural flow.
