OK, firstly the splash is HUGE, it takes a very long time to load even over my school broadband connection and it would take about a minute on dialup.
Next. You're using Simple Plan, big props for that. *is almost as obsessed about SP as she is about Good Charlotte* My favourite song, too. *dances around singing it for ten minutes*
You should change the font from default to Verdana or something similar.
The main content bit spills over into the nav bar. Also it starts right on the edge of the white bit and that doesn't look professional, you should allow a margin there.
You need to put some space between the contact box and the stats box.
The stats box is narrower than all the other boxes in that column.
Besides that, it's OK I think.
