It is too dark. I could not read to the middle of the first paragraph before i gave it up. If you do want to keep it dark then increase the font size and make it more contrast to the dark background. You have couple of glitches on the right side - the text goes outside the borders. (see it with FF3)
It's free joomla template, not sure about 'your first design' Or you've created this template? looks ok, except what stevestuff told already.
Great design. I'm using Firefox 3.1, I found that the content is overlapping the right border and also the underline of the title is overlapping the border of the site.

Chester, Your web server seems not to understand index.php. When I go to your site I can see the directory structure of your joomla site. I have to click your index.php file before I can see your index page. This is very insecure.
