Jorge,
You have some strong images on your site. One thing that is distracting is the credits which appear at the top of the page.."Web Design by...". Do these credits have to appear in such a large font? Could they possibly either be shrunk and put on the bottom of the page, or have your credits listed on the About page instead?
I'm just thinking moving the credits to the bottom or to a different page would allow the viewer to focus on your images.
