Hi,
Pretty nice website... I used to write websites for a living so I can't help but look at websites in my design/development mode... so sorry if I'm a bit heavy.
Firstly... your images are superb so keep up the good work!
I think it's very simple, easy to read and easy to navigate which is really good, this is something that most people get wrong, so congratulations on getting your navigation right.
A couple of things that I think will improve the site though. Firstly, I will recommend removing the scrolling marquee with your website name and possibly replace it with a graphic with the same text or a logo with your site name.
Secondly, the primary purpose of your site I presume is to display your portfolio, so when your site loads to need to make sure all your critical information is in the top of the page so users don't have to scroll, web users are very impatient so as developers we must design and develop for this.
So for example, I see you mention your geographic availability, maybe move this further up.
I would post a screenshot but I can't upload attachments, but PM me if you want help and we can chat about it.
