Really nice page.
Wench is right about shadows... I don't use the predefined shadow setting... because it's too dark.
I very often change the default by:
14 - 45 - 12
When I want to get a 3D effect.... I change by: 30 - 60 - 60 and sometimes more...
You might play with the settings and then zoom the page to see if you get the expected effect.
