I have to agree with Santa on the facts he pointed out, the landing page is just an additional step that may drive away your traffic. You also may consider investing into a jQuery tab plugin to make all of your gallery available to just be sifted through, rather than having to reload the page for each one.
I like the look and your photos. My constructive criticism:
* There are a couple run-on sentences in your first page. I suggest you place a period after the word "homes" in the first paragraph, and start a new sentence from that point. The next two paragraphs would also read better if they were broken up just a bit more. See if you can break one of those long sentences with commas into two separate thoughts.
* From any of the Gallery subpages, the link back to the About page doesn't work. It goes to an error page.
