Sticky icons - Preview

This is a preview of my WIP dock icon set, my take on the web 2.0 sticker icon concept. Looking to get feedback on current icons and other icon ideas, like other software or websites.

Icons I have done but are not in preview:

Firewire HDD
Apple HDD
Windows HDD
Gmail

I would like to make this a fairly complete pack, so please let me know what icons you would like to see!
