The header is a bit busy. Eyes and random lines/geometric shapes are a little overdone on the web these days for designers. Simplicity will always get your farther.
This might be a heavy suggestion, but I think it will make your header look tight:
I would recommend dropping the eyes with the catch phrase overlayed on them, drop the hexagon on the right with the triangle, and drop the two random lines. So now you are left with your logo/lettering, the blue anti-aliased background with the computer photo.
And . . . we are going to go ahead and drop the computer photo out of there. I am a huge fan of fine art stock photography. You want to make your potential clients feel refreshed . . . a computer doesn't accomplish that. So go find some great fine art free stock photography that is cool (you should know cool, you are a designer) - I would recommend this site:

Keep the anti-aliased style blue overlay - and just put a photograph underneath it aligned so that it looks "cool" and adds a certain level of depth to your site. If you want to take it to the next level, setup several of these photo "backdrops" so that when you go to each page it pulls up a different backdrop to your header . . . and you can even correlate them with something to do with that page.
Anyways - just a thought - might take some work, but I think you'll like it.
Enjoy.
