Refining the Windows 8 Modern UI Tile Icons

Had some free time so I decided to refine the icons of Windows 8 Modern UI Live Tiles. Had some pet peeve issues with some (if not all) of the app icons, specially the News, Camera and Map Apps :)

The existing icons are good, don't get me wrong. These are just some of my own suggestions on how I think they can still be hopefully 'improved'

Brief explanations was featured here on this site. With side-by-side icon comparison: Polishing Windows 8 ‘Metro’ Live Tile Icons

What do you think? Any comments? Suggestions?
