I prefer this design, Andre. Seems cleaner, and the background color works well. I still had to scroll down a bit to see the Sertao portfolios, but the rest worked fine. Could see the photo and the arrow button, which is all I ever want to see when I'm looking through a web portfolio. If you have the time and patience to get rid of the white strips, it may well be worth it. Sometimes, what works on paper prints, doesn't always translate well to a web presentation.
One tweak... when I opened up the motorcycles, it started me on picture number 9 of 10, so I went through it backwards. Not sure if I did something wrong or not?
Also, I think some of the portfolios would look stronger with some tighter editing. Under portraits, you might think about deleting one of the two dog portraits, and in landscape, the cans or bottles in the pond look repetitive, pick the one you think is the strongest. Oh... and the one color image seems a bit out of place. It's a great image, but it such an about face from the rest of the portfolio.
Also, an "about the photographer..." page is a good idea to have.
