On the flip side of the coin, I would say don't attempt to customize it. LaTeX out of the box is essentially what you need for an easy to read document.
There is no LaTeX graphic designer out there. I would agree to a little defeat and say the poster example on that website looked bad. If customizability is something people are looking for LaTeX is not the ideal choice because the learning curve for advance use can be incredibly steep, you may not have a good eye for good graphics if you are using LaTex in the first place and you might compromise early and say good enough.
