Hi,
Sorry, I typed you out a long one and the site lost my login so I had to start again.
I would have it set up so that when you click on the slideshow at any point you go to your gallery. At first I didn't see your gallery and thought it was only a slideshow. Not very observant of me, but then some people aren't! Better yet put some of your best pictures from different categories and a bit of text as your homepage, have every image link to its place in your gallery and a bolder link into your gallery. People make their mind up quick and if the first photo in the slideshow isn't what they're after and there's no description they may just leave. The gallery works very well, though the categories could use some work to make it simpler/easier to find what you're after, if at all poss.
Your metadata keywords aren't excellent. And worse they're the description to your site on google, I presume because its all flash and you don't have the correct set up in metadata or a html version of the site. I find it helpful to search google using terms the kind of people I want to attract to my site may use, click on the first 3 and view their source, get ideas from their keywords. Keywords aren't as important as people would have you believe, but for the hour or so it takes to put down some good ones they are worth it. You can also check out their sites design and layout. This is of course if you want to attract people to your website to get work, I got that impression from your about page, but it seems like you're sitting on the fence a little bit. Personally if I were you and wanted work I'd go a lot stronger on the about page.
Check this site out:

Sorry if I used any incorrect terms I haven't done anything web for a long time now.
Your photos are great by the way!
