First the good. I do like HDR when done tastefully. I feel many of your images are in fact tasteful. As someone who shot interiors for designers using film and a bunch of lights, I think HDR for interiors, providing it doesn't change the overall color scheme and feel, is a fantastic alternative. I come from a line of analog work and teaching and still feel I appreciate the digital age.
Overall, the site navigates very well. I am not really confused about where to go and what to do. I think the tagline about HDR photography made easy isn't fitting for what you do. Unless I am mistaken, you would like to photograph various subjects and that is how I think you make your money. If that is right, why try to make HDR easy? Now, if you want to use that tag line in the area of the site where you share your technique, then that makes sense. Maybe I am reading too much into things.
A couple of things I noticed; the font color is difficult to see against the white background in "HDR Photography Made Easy." At least to me. Also, there is that image on the bottom with the moon. I get the whole SC crescent and such, but the image is very 1995 bevel/emboss/drop shadow. It doesn't flow with the rest of the design, which I see as minimalistic. Also, I would be sure you do not use too many fonts on the site. Choose one, two maybe and stick with it.
Again, I think I'm a fan of the design but more so, a fan of your work.
Side note: I want to stay in that hotel overlooking the golf course, if it is a hotel.
