This looked like it was going to be a bit of a slog but it all came together quite beautifully.
Great fun and a thematic tour de force.
Many thanks, eXternal....
An elegant composition with interesting background material but it all fell into place rather too quickly giving massive help with the back solving.
Thanks, Craft....
Very clever but there was insufficient connection between the thematic clues and their entries.
All the same were introduced to a few interesting words.
Thanks, Stick Insect....
A great theme and also a personal favourite.
The final instruction is still a bit confusing although it didn't hinder the final grid fill.
Thanks, Ifor....
