Concerns about Proposal Paper

Concerning my Proposal Paper Draft, I really think I need to make modifications to my thesis statement. After writing my statement, I made changes to the body and justifications of my paper, and I need to make the corresponding changes to my thesis. Also, I need to include the "so what" part of my thesis. Additionally, I believe I need to re-read my paper and check the mechanics and organization, and make sure my conclusion ties up the paper the way it should.
