Some Things to keep in mind:
Photographers love first looks for a few reasons. First, it gives the couple that quiet alone time before the ceremony to really be present and get some sentimental photos. Second, it saves a TON of time as far as the timeline goes. With a first look, you can take the majority of your couples portraits before the ceremony begins, so that we aren't crunched for time after the ceremony before the sun goes down.
I always recommend that you plan for your ceremony to take place at least 2 hours before sunset. After the ceremony we have two key things we need to get: couples portraits, and family portraits. If those are pushed back because of timing, we could end up in the dark (and no one wants that!)
