The most obvious thing to me was the "Welcome to our site" in english
With a spanish name, you would kinda sorta expect the default to be spanish..
Also. Site too wide. Shoud be variable depending on the visitors resolution. Lose the image in the top section, insert a table(s) or div(s), use a background color instead, put text or smaller image of text in top left to replace the "welcome to...", put image of top of the peoples heads in the center one, etc. that would do it. You may have to re-slice your design to do it right.
