I see you are using ‘All in One SEO Pack’ – good. But check the details. As noted above, your title pages are all the same.
I think your site looks very good. Except of course for the header which too dark.
I just recently changed my site too ( Casino Bonuses ) . Like yours, I choose to give it a simplified look.
99% of the people will disagee, but I now use a casino ad as my header (no logo)
