First off, I'm a landscape/nature/travel photographer. I mainly sell prints of my work. I'm in the process of redesigning my website, and I'm trying to decide whether to keep the navigation extremely simple or leave the drop-down menu for galleries. Currently, my navigation is something like this: Galleries
 > Gallery for State or Country (example: California)
  > Sub-region in State or Country (example: San Francisco)
Blog

Contact Selling prints is the top priority of the website, as that's what runs the business. I have lots of blog content, and I'm starting to build some good travel advice, etc. but in reality, the galleries, which then filter down to individual pages for each photo with a cart system, are the most important. What I'm struggling to decide is whether to leave the sort of "mega menu" for the galleries, or to do away with them, and have the user go to the overall galleries page to navigate further into the site. Leaving the mega menu intact, the galleries page becomes a lot less important, and takes out a step to get to the shopping cart. However, I'm wondering if the amount of galleries in the drop down menu is giving TOO many choices up front as well. I also wonder how changing this will affect search. Any thoughts on which is better or is it really just a matter of preference?

I just signed up for Moz recently, and have noticed that in my crawl errors, I have hundreds of issues with my title tag being too long. My business is selling prints for landscape/travel/nature photography, and I've built these pages dynamically to where the title tag for pages selling individual photos has the title of the photo for sale followed by a hyphen and then the brand name. The same goes for gallery pages "Gallery Name | Brand Name". Would it be worth it to shorten the title tags by removing the brand name from these pages? Or will that actually harm more than help? Thanks in advance!
