There is no focal point, and I don't think adding content will fix that. There is no structure, and is bland in look and feel. Try new placement of your logo and nav. Add some "fake" copy and headlines so you can get a sense of structure.
Wonder what it would look like if the photo were bigger and placed on top of that "highlight" in your background and then that was boxed out and your entire background was just black and you could use the bronze coloring as an accent?
I do agree that it is infact too dark and has no focal point. The content was supposed to be the focal point but who knows. It just came out extremely dark for whatever reason. ill try to liven things up. I was going to make a white(or lighter colors) and blue version of this same layout.
Why does the site have to conform to the standard web layout (Home, About me...). You should look at making something a bit different and unusual if you want this site to be different from other doctor sites, However it needs to clinical and corporate enough for people to want to come to him for advice. At the moment he looks like heis more worried about his looks, rarther than giving me a prostate examination. Dont mean to be rude, but I need to feel like I can trust him.
Looks like something for a model and not a doctor. If you want it to be dead obvious, kill the brown and go for a medical blue-green. I think you skipped the research step in your design. Look at this doctor's competitors, local hospitals, or even bigger hospitals or doctors in other areas.
