Here are some forms of Eye Catching Ive done for NON porn sites.. But the idea is still there...
Look for the focus points..
A Live site
http://sigil.betagamer.com
Soon to be live site
http://watchersrealm.betagamer.com
Focus points for the Sigil site, is the Granite Statue on the splash page, and as you enter the Demon creature next to the logo.
The just slpash page on Watchers realm, is the faded person in the background.. "A tease" if you will.
(yes I still do contract graphics work for cheap)
