Have website, need graphics skills

Recently I have found myself spending more and more time on various graphics/design-sites going over their tutorials, desperatly trying to mimick their looks, feels and styles. I've followed tutorial after tutorial, studied one wallpaper after the other and I still can't get things to look the way I want them to. Dammit! This site really needs a graphical overhaul - I am far from contend with the current looks.
