Well.....I personally find the main page a little too busy with all the thumbnails. I'd rather see a cleaner front page with the thumbnails for all the photos available only through the links at the top. I really do like the links at the top for each section and how they expand when you mouse over them though.
And.....of course, your photos are excellent, though I'm sure I've told you that in one of your threads before....even more amazing that you get such incredible photos with the basic setup in your sig.
