Ok since me likey websites and im always like to critise(sp) them as well. i wont get into spelling because i cant spell either.
but a few things to think about.
I like your drop down menu's but maybe make a page for if you click on the main button too. so as an example you would be able to click on the "process" button and that will bring you to a page with the links to interior and exterior as well as the drop down menu. the reason why is that some people turn off java script somtimes. who knows why but somtimes they do and then they wont be able to navigate through your pages.
Then a another thing i saw is that you have no footer. the page just ends with writing. maybe think of making a footer. you can model it off your header but just shrink it horzontaly and make it less complicated. even if you just put a email link and ur name and copyright by: and all that stuff. but it should end with somthing.
Between the text and your pictures....like on your homepage where there side by side. think about putting alil space in there. here is an example of how to add it into your html code.
<img src="img/home.jpg" border="1" align="right" hspace="10">
Thats all i see for now.
Overall very nice layout very clean and organzied. love the photogallery
Good Job.
