I agree with the other comments, particularly the lack of themes for the photos and how slow the site is.
I found your portraits slide show to be pretty annoying. I have dual monitors, and if I leave the cursor on the monitor showing the pictures your banner drops down and obscures the tops of the images; I have to move the cursor to the other monitor to see the whole image. Many of the photos have nice poses, colors, and lighting; but just as many are simply out-of-focus images that could have been taken with a cell phone; cull the poor ones out.
The other point that I found a bit at odds was the discordant sound between your site name and your narrative text. "The Picture Doctor" is definitely singular, but when I read your text entries - for example your "About" section - they are full of "We shoot...", "We believe...", "We are...", "We spend..." etc.; it sounds like a one person show trying to sound like more than they are. It may just be me, but I would make the site name plural, or rewrite the text using "I" just for consistency.
All this being said, I still think you're off to a good start; however, as it stands, your site wouldn't inspire me to actually contact you for your services.
