The website looks brilliant! However, the splash page is out place. The "Viva la programación" is in your face and not in keeping with the theme of the site. The site seems to have an abstract flat/print style to it and the grunge style of that hero image is out of place.
Another problem with the splash screen is that the menu bar elements seem to change size and position when hovered upon in a smaller window (<960px).
I do know the home/splash screen is the hardest thing to do usually (design wise) as it will be the first thing a user sees when coming to the side for the first time.
