I made a slight tweak to the clue to make it clearer, thanks! (Normally you wouldn't see this on one tag, it would be a list of sizes). This is what I get for forcing that little bit of fill in there :).

I tripped on this too, even after the clarification. It was my one bad square after filling in the grid (SMS instead of SML). I really enjoyed your puzzle!
Nice! Would have been great to see a revealer of some sort to tie this all together. Also not digging the use of "not" in the clue for 19A since it's part of the answer.
