Structurally I think it works well, but as the structure is virtually identical to my updated [but not as yet uploaded] site and quite similar to my old one, I am biased.
Some very nice shots on site and they load fast enough, but my niggle, as with all to many photographers sites is that the typography is somewhat weak and lets the site down. This is a common problem if you do not use image based text when doing web design as browsers and OSs render type somewhat variably.
A smaller point is that when you scroll down in Opera a white bar appears at bottom, but not in Safari or Firefox [on a Mac]. Not even sure why the pages even needs to scroll as page is completely visible on monitor.
Chris - Complaining about installing a Flash plugin is ridiculous, as if you want to view the web, you are limiting yourself without it as Flash is so ubiquitous. Hence the very high installed user base. And Flash isn't slow, it's how it may be implemented that may be slow, there is a difference, HTML or CSS can also be slow if there's a lots of big images. Used correctly it can be faster than HTML.
And Flash is also very handy if you are concerned about getting typography right and the site looking the same in all browsers, which is certainly still an issue with CSS.
