Um, I feel the entire approach is questionable...both, what Steve already has and what you are proposing...
Sorry, but honestly both of them fall short of what Stevepavlina.com is actually about. And instead feel too heavy and kinda cheap.
The change in colours and gradient don't make a whole lot of difference in my opinion. You alterations are definitely an improvement on the aesthetics of it, but this seems more like decorating then designing. I mean it doesn't add value to the content of this site.
