40 mins today didn't have to use a Thesaurus for any of them either, probably a first. Only used Wikipedia to look up Monet paintings as well, which turned out not to be the answer anyway.
Had to come here for the correct parsing of the second word of 11D, but the answer was clear.
19D probably took me longest to get, but weren't the last ones in, which were 13 and 25.
19D and 20A probably my faves.
6A made sense to me: inside (French + Quietly) insert (Left duck).
