This group of girls may be a little more artistically appealing. Maybe I'd learned to use the brushes in my cracked version of Photoshop.
Or, more likely, it's a move away from what we used to call "web-safe" colors. If you look at the previous version, they're all solid blocks of simple colors. This group has a softer feel with lighter colors and shading. This was my favorite version of the site, and it stayed up for over a year.
