Very good layout, love the colors
I like the design but i think there are too many rough edges. maybe try smoothing and rounding the conrs off to give it a more pleasing look.
The design is clean and simple, but you may want to move the text on the left-most tables over to the left more, as they are hanging close to the edge of your background image, most obvious in the links under "Online Websites".
You may also want to create more of a padding on the right of the text in your headers, for they are pressed right up against the edge, creating too immediate of a seperation.
Just one thing, i wonder why no one mentioned it yet, its about the color of the main text in the middle, there is not enough contrast and at some parts its unreadable when the grey text is on top of the grey areas with the noise textures in background.
I didn't find the grey-on-grey distracting at all; the two values are noticeably different when reading.
Listen, there ain't nothing better than a designs that is just clean and simple, and the navegation can't get smoother than that.
Suggestions: On the 'Online Links' I wouldn't add the 'http:// or the www' just put the site's name and link it properly. Other than that is looke pretty damn good. Good job man.
