It does load quickly. I like that. I also like how it all fits on one screen and I don't have to scroll. One navigation design item I might add is on the FAQ page. Currently, when you click on an FAQ item, it does not have a link back to the list of FAQ items. I would add that.
I keep thinking the header isn't quite done. I would make that black rectangle part fill the entire rounded rectangle. That would look more finished I think.
The Joomla credit on the bottom of the page is both distracting and quite hard to read. To remedy this, I would put it in a lighter color and center it under the block rather than having it aligned to the left.
Nice site, though, keep up the good work.
