Love the concept, I'm a big Ralph Lauren fan but having the same icon for everything would drive me insane. At the very least chance the color for the icons for different apps. Also I notice that the page indicators are a little hard to see. Maybe you should check out this page
Hack that Phone - Make and use themes with WinterBoard - Section 12: Changing the SpringBoard page indicators so you can learn how to chance them. Fashion is important but don't forget it has to be functional and the same icon for everything is not functional. Also once you get some icons going over that Ralph Lauren logo it won't look very nice, maybe you should see if any nice person would be willing to make a small mod so you only have 3 rows so nothing covers the RL banner. But it is good keep working at it and it will make a fantastic theme.
