Adobe Lightroom redesign

As a designer+photographer, I use Adobe Lightroom most of the time. And as powerful it is, it's UX can be improved hell lot. So, here's my redesign of Lightroom, which I did on my spare time. I've tried to simplify the navigation and controls, while keeping the same level of functionality. Don't forget to check the real pixels and let me know your thoughts.
