First thing to do is have more information. Your about page is just a photo (assume of you.) That is interesting, but the very first thing I want to see when I go to a photographer's website is where are they located. From your website, it appears you are in Houston. A potential customer should not have to search for where you are. It should be obvious.
If you are a full time photographer, which it appears possible, list a business telephone number at least. Younger people are used to contacting people by email, but older people want to contact someone in person or by phone at least for the first time. To me no phone number also means the business owner has another job and this is just their part time job. You may lose jobs from people just because they would assume you are not available except after hours, weekends, etc.
Your blog needs more writing. As it is now it's not really a blog, it is just another type of gallery. Photo blogs would be fine if you didn't already have several galleries, but as it is now when customers click on it, they will expect to read about your photographic endeavors, not just see more photos.
Other than that, the photos are great. On the home page, a couple appear in two pictures one after the other. I would suggest only one photo of that couple on the homepage. Seeing them twice looks like you don't have a large selection of photos to pick from in making the home page. In my opinion, that makes it look like you are just starting. But, you have a varied enough gallery that does not appear to be the case. The home page may be the only page a client may look at, so it should be the most important page on your web page. Also, if you can, try to move up the photos by getting rid of the dead white space.
