Windows Phone notifications history concept

What do you guys think of this concept made by a guy named Kasser Riaz?

Personally I think it's brilliant. The notification screen looks clean and easy to read. I love how the tiles have different colors like in Windows 8. I'm not a big fan of gradients and fake mirroring/glass effects but it would give the UI a more polished look that would probably appeal more to iOS/Android users.
