Not too bad.
I wouldn't have the pc icon the notice alert suffices imo. With regards to the colour scheme. I'm not a fan of blue, in particular the actual blue in the mockup I don't like, I'd personally use a myriad of colours rather than dominate the style with blues. Try getting some other colours in there to break the theme out a little giving it some character.
Menus are a nice touch. Nice work but get some colour in there.
