Hi Gerald. I have had a good look at your site and here are my observations if that's ok.
It looks a little bare, unless you are going for the minimalist look!
In your "about me" page maybe add a nit more info as the visitor doesn't really get to know you.
Why not add a "in my bag" type page. I really like to see what kit others use and I'm sure I'm not alone on this. You could really go into depth and add links for your kit.
In the same vein, how about a review page?
I really like your images but the portfolio page looks a bit " amateurish", I would have the text beneath the thumbnails if it were my site.
Add a guestbook page.
Overall I would like to see a blog page where you could link images and tell a story about the day, the weather, lighting etc.
These are just a few personal opinions and it is your site so you have to be happy.
Andy
