Thanks again, Pete. I'm unashamedly pleased with this set. The first one, the "Open" sign, just caught my eye - I saw the humour immediately. The janitor behind me just stared at me as if I was an alien - that convinced me I was onto a good thing! The venue was so photogenic, both the architecture and the exhibits, that it was a bit like shooting fish in a barrel.
If I were to choose one, it would be the last, for all the reasons you mention, plus the framing. Very pleased with that.
A good day.
