League Champion Concepts for School Assignment

For a school assignment I was supposed to make a proposal to a community and add elements of design to the paper. I finished the class and the assignment did well, but I decided I wanted to post my ideas to get some feedback on the concepts and to get my ideas out there. There are a lot of concepts so reading them all would be quite the task, but I'd still love some feedback!
