Looks good for me, navigation is hard to reed. And looks like a landing page. Maybe adding more features.
The more important aspect in your theme is typography, need a lot of improovements.
I like but like bellson said i think this needs some improovements, based on typography and alignment. And try to add some unique concepts to the design.
I think is a good idea with a quite bad execution, the menu effect is good but design looks a little bit outdated.
I agree with charlie all basic design standars need improovements.
