Didn't setup mine yet because I will get the Lumia Icon in a month, however I been playing with the setup of the home screen using the same programs from my current HTC 8X and make the new alignments to the columns.
I prefer the light background and Cyan color for tiles.
To change the colors of some tiles I'm using the app "Cool Tiles" (whatsapp, iexplorer, app store), to make the groups I'm using "Group Tiles", for some apps I'm using the app called "WebApps", some other things like music I'm pining some of my albums and Pandora stations. (for the Photography section currently I don't have Camera apps from Nokia), I have more sections called "Outdoors", "Work", "Tools & More" not showed in this picture.
Here is the a picture with sections:
