Critique my website design

Hey everyone!

So I'm getting started in the web design area (trying to start selling sites around my city) and want some feedback over how my "portfolio/company" site is looking.

I'll be adding some effects to the slider soon, and some minor tweaks around, but that's mainly how the home site will look (and basically how the other pages will, too).

Any tips/pointers are gladly accepted!

Cannot see anything!
