1. Like the header, but think you can make it smaller, thus bringing your content higher up, when a visitor clicks on it. The black border distracts from the page.
2. I would make your sub-title either the color of the title or pick a color from your graphic. You don't need to underline the sub-title. The sub-title also repeats the title....try to pick something more constructive to describe the content.
3. You have ads by Google in three different places. Like Lisa suggests, make your ads the same color as your major links, to sort of hide them. The black horz. bar with Google ads at the top is distracting. I personally don't like to find ads near the top of any website.
4. The Google search box is too wide.
5. The first graphic in your content is again, way too big...you want to get your readers down into the meat of your article as soon as you can.
6. Again, I don't think yoiu need the border around your content...distracting.
7. Not a big fan of Donate buttons. Your use of Google ads three times and the donate button, tell me, that your more interested in making money off of ads than supplying quality content.
8. The black and gray navigation table just doesn't compliment the page. Again, I would try to use some of the colors in your title graphic....

9. I would add your copyright notice and/or privacy policy to the footer.
10. Great idea, with a few tweaks...Good luck with the new site!
