I like the layout of the design and i can see where you're going with it although there are a couple of things i dislike such as,

• Navigation Buttons:
  They are really big. Yes, you want them to stand out but not like that. You may also want to think about lowering the opacity of the scanlines on them.
  
• Banner:
  I don't like how the banner is black and white. It would be better if you added colour to this, make it stand out a little and match the rest of the colour scheme.
  I'm not to good on fonts but i'd suggest changing the banner font and decreasing the size of the text "Your Company Name".

Appart from that, it looks great. Keep up the good work!
