OS X Metro Icon Set

In Progress: OS X Metro Icon Set! Closely copying the features of the usual icons, but with no layer styles and with 'flat' design. All of the icons in the image are part of the new set with the exceptions of Mission Control and Calendar, which are not finished yet. Some of the icons, such as reminders and Photo Booth (which I'm particularly proud of!) are nearly indistinguishable from their normal counterparts at small sizes. Please let me know what you think, and if I should finish this set, as well as what should be changed about the existing icons. Thanks!
Edit: As requested, here is a link to a dropbox .zip of these icons in 1024*1024 png format.
