Fair enough. 12a is actually INTENSIVE.
I'm not very happy with 22a. To ABSTRACT can mean to summarize, but that's not really the same as abbreviating something. Or is it?
Then there's ARTILLERY for troops. I don't think artillery can mean a soldier, though artilleryman can.
14d should really say "intended's collection".
As I've said in a related thread, I think some of the clues are suspect and unfair.
