Is the strongest of the two, however the colour scheme is a bit dull.
I like the blue, it gives it that certain blueprint feel.
not too keen on the dark beige grey colour, I don't think it compliments the blue all that well, suggest that you go to kuler.adobe.com and add your blue colour and then see what colours compliment it.
Also, would like to see how the navigation is going to work...
Overall it's a good start...

Thanks for the kuler tip, will check it. However, I was thinking about high contrast using that dark beige. I will try to use some cold "steel" gray background, instead of beige.
The navigation should be pretty simple, using the top menu for more important pages and footer menu for the rest of them. The only fancy thing I was thinking about is a hover effect for top menu, that's it.
