Clock's a bit big. Top icon row could be a pinch lower, but it's such a minor thing, I wouldn't give it a minus.

Awesome. If you used more icons, you could make use of that vacant space.

Personally, I would space the two bottom icons more apart so it looks equilateral.

Very clean looking, unlike many layouts here. I don't think the icons need to be pressed right against the screen's edges. And while the icons look OK, maybe solid white icons would suit the clock and App Drawer icon better.
