Place your credits (once you have some images to credit) at the bottom of the hub, not at the top.
Move the polls to half way down and to the bottom before the credits. Don't use too many, I would suggest you restrict them to two or three, max.
Start with a proper introduction. Then a picture underneath. Then the discussion.
I have to say that I find it hard to understand what you are trying to say because of the awkward phrasing and grammar. I think you are making really good points, but they are lost among the tangled sentences.
