I think that you could utilize that white space in the left side of the header. Maybe add some images.
O...K.....!!! tooo much white space dude....and NO ads?????? the design is good...but u need to fill the empty space with something...either ads or pictures...
The site looks good it's nice and clean and easy to navigate but I agree with what has been said thus far about the header, you should add some graphics or and ad into that negative space in the header.
hey, its simple and also formal.tags and links are legible.keep up the work. try to add some appealing colors and little graphics so as to make it youthful.
It looks allright for me, maybe you just need to fill something that looks a bit empty on the upper right of your site...
