I actually think the Crucible design is the least literal of the two. I looked at the Crucible theatre posters online, and most of them were figures hung from trees or girls dancing around a fire, I wanted to stay away from those sorts of things at the risk of copying.Not necessarily abstract, just less literal. You only need to Google 'The Crucible Book' to see what I mean, sometimes things can be inferred by using right image.
The Private Lives design, I agree is very literal!
Anyway, thank you for your advice. Always appreciated.
I've decided to put this to one side now. I'll post any new versions if I revisit it.
