Id include a little flash as that always looks really nice for a photography website but its clean and to the point... its a nice start for a website... from where you are you should be able build it out into a site many people would like to see.
Gallery should be done in flash. 1. You say it's bad for SEO. True but you can combine flash with another technologies for having anouth of content. 2. You say it takes much time for loading. But if flash is dynamic then it will take almost same time. There are huge amount of flash photo galleries and they are very good. So this gallery is good for non-flash site but it could be much better with flash.
Nice site! The only thing that bothered me is on the homepage, the photographer's name is smaller that the tagline. I like how you stretched Photography under the name, but I think it should stand out more.
