I like it, Leon.
The thing with websites, is they can look good or even great but a lot of them are just boring. Yours has content (more than just a gallery), which makes it interesting.
It's aesthetically pleasing, easy to navigate and you have interesting content, especially with the PDF articles.
I would like to see the images a little larger, but having said that, I've just replaced my monitor and switched up to 1400x1050 after looking at 1024x768 for years, so everything is smaller. But yeah, bigger please!
Also, the 'Contact' link threw me with my email client popping up. I've gotten used to using gmail in a browser and Thunderbird has become an archive for my older emails.
I'm looking at it through Firefox 6 on Linux. The site scales nicely when I resize my browser (so many websites won't do that) and I don't see any problems with layout or anything.
