I'd probably get rid of the "search" and "browse" options, they are cluttering and serve no real use to the average visitor. Your galleries are your default way to "browse" and should be!
I would consider adding something personal beyond your photos, if only an "about" page at a minimum. If a rando were to find this site and really liked the work, they would probably want to know a little more about you. Same with a "contact" page, I've made some great connections simply from having a means for someone to reach out.
I'm sure you've poked around my site a time or two, but I'll explain some of the reasons I made it in the first place, ranked by order of importance to me.
1) A permanent, public repository of some of my favorite shots
2) A way to connect with people both on the creative side of the community and the business side
3) A repository of opinions so that I can simply link to my exhaustive thoughts on a subject instead of rehashing 100 times
4) A way to sell prints (very small part of why)
5) A way to provide some passive income (becoming more successful than I realized it would)
The thing that drives traffic to my site passively is my blog, simply because Squarespace is very good at SEO in the background. I get about 12,000 visits per month simply from people looking for a review or opinion about something. That they see my photo galleries is a plus to me, because they would have never found my site otherwise.
Making a blog post is really no more effort than making a long FM post at the end of the day but the ROI is far higher than posting it here
