The photo walls are ok, but they look really cluttered to me, and I completely agree on the RH edge. I thought there was photo missing in the second row of wedding photos. I'd take the Instagram link off the bottom.
You only have 2 photos on it, so there isn't anything for someone to look at.
Once you get into the large-image mode, there aren't any navigation clues to tell the viewer that he or she can click to move to the next image.
I would try not to use the same image in multiple places on the website (for example, in your portfolio and on the contact page), it feels like you don't have enough to fill out the page.
You have some weird crops on the landing page. I know that is a very strange size to crop a photo to, but it doesn't really work for me, and it is the first thing someone is going to see.
I would also suggest some additions to your wedding portfolio. I see a lot of portraits with over the top lighting (it is done very well and looks great, that's the just best way I have to describe it). However, there aren't any images on there that show that you can capture a ceremony. If I'm going to pay you 3,500+ for my wedding, I would want to be able to see that you can actually cover the event, not just pose the couple in a couple of places***
***There are a few photos on there that do appear to be from a ceremony, but they look posed too (have the couple holding hands, and just altogether look similar to your portraits) or have foliage in the front that is being used to frame the person.
