Personally, I find the use of many different font sizes off putting. I would prefer to see ALL the text in a standard size. Simple titles/headers could be in Bold or a different size, but I would much prefer NOT to see paragraphs in different sizes.

Sorry to say this, but it looks like you've cut and pasted the text from many different locations, and not changed any of the original formatting.

I didn't have any problem with the original navigation, but do dislike the little hand pointer. It makes me think that only one section is clickable. Again, personal preference, but I would lose the hand.
