Looks great! Compact, intuitive to navigate, all around very nice.
Just a few things:
There's no "home" button and the main logo isn't linked to the home page either, so other than the "back" button, there's no way that i've seen to get back to home.
The nav bar could benefit from a mouse over color change, just to illustrate that the tabs are actually active.
The cow could really be used as favicon as well.
Once on a tab is clicked, the body of the site turns a bit too gray, maybe a backdrop color behind the gaming systems would freshen it up a little. Nothing too obnoxious, just a subtle color change should do.
Remove the "Your Ad" boxes and replace with your own promotion. The blanks space also translates onto your site and deliver the impression that there's nothing going on. Instead, replace 2 of the blanks with Contact and Advertising, that should do for the beginning.
When accessing your site through egotmilk.com the site still shows under development/coming soon. Maybe you should consider bringing the site to the foreground directly at the main url without any add-on of "index.html"
All the above are really only minor adjustments, the main build, appearance and functionality are great!
