I am a web developer / designer for the last 10 years... so I hope my feedback would be useful to you, sorry if being a bit harsh
1. The portfolio images cycle too slowly for me, I wish there was a way to control the next/prev images in the list
2. Your 'home' page does not do much for me as it is just a static page. I would actually use your "portfolio" page as the homepage because at least it is doing something
3. the email link on the contact page has bad contrast with the blue sky - I would suggest putting a contact form here - also to protect your email address from spam bots
4. some of the galleries only have 2-3 pictures, I would add more to make your portfolio seem more diverse
5. on the homepage, for SEO reasons, I would have at least a blurb about you and what you do - it will help search engines find your site and its contents.
6. the "live" link is a little out of place for me, I know you want to focus on golf/landscapes, but the live music portion seems out of place, maybe change your company image to "golf courses and events photography"
7. I have a 1920x1080 monitor (as more and more people will have these days as costs go down), I would make your site's width 1000px (as it is now 700px), so even on a mobile device like an ipad, it would look good full-screen. This way the images would pop more without the need to 'click-to-enlarge' which you don't have anyway
Other than that, nice layout - I like the minimal approach
