I'm not really sure. I am not a great web designer (I use simple designs), while her designs are far more attractive and sophisticated. Her site is very graphics-heavy (by necessity, it's a graphics site) and she uses a lot of graphics for navigation, while I use text links.

I was shocked at her page views vs. bandwidth because I also have some graphics-intensive sites too, yet my bandwidth is so much less. But I design things simpler (people with old computers and browsers can still view my sites), so perhaps that accounts for it. I guess there's something to be said for keeping things simple and unsophisticated!
