After recognising that I was going down a dark path by spending way too much time on this landing page, I decided to cut all corners and smash it out in it's simplest form (just one screenshot, and using FormKeep to capture email addresses). It's helpful to think about landing pages as an iterative process (i.e. we can always make it better later), it takes some of the pressure off getting to a big Tada! moment and helps prioritise just the critical things needed for a first launch.
