Retrospectively I found this very enjoyable, but I did founder for quite some time on the way to this point! Thanks Fer de Lance.
I enjoyed the endgame and found it very clear, which I appreciate after a tough grid fill. I don't agree that there's anything unclear about the instructions or preamble. I thought the clues were quite actively misdirecting (in a good way!), although I don't rate 38d I'm afraid.
Anyhow, a well constructed puzzle - thanks, Fer de Lance!
