Spelling a few of these words is the trouble I have. But I don't think that'll hurt the puzzling experience. I'm eager to hear your comments!

--oops on the misspelling, and thanks!
--glad to hear of the chuckle on 16D; gotta think even more on the surface of it.
--I leaned into the alliteration over the surface on a bunch of these clues (incl. 22D); wow, to get good alliteration and good surface -- that'd be noteworthy!
--yup, a lot of anagrams; I noticed, too. I'm starting to keep track of my clue types, looking to even it out better (also trying to keep the location of the semantic part of the clue even between beginning and end).
--I like the "two queens" idea (though in my day it was "jacks or better")
--I tried an &lit for 5D (as indicated by the "!"); maybe I needed to prepend with "for example." I've tried to use "for example" in the semantic (my word for the definition part of the clue) in appropriate places.
