the first detail i saw was that you did not change the background-color of the tcat and thead, so when we hit the site first, if it lag a little, we see blue everywhere... would be good to make the color fit the image...
your bbcode tags are not fitting the width of your page:

lists are better balanced to the left, not centered, this announcement look strange:

the default color for links is basic, would be better make them fit with the style colors...
