Cryptic crossword No 1,945

Welcome back Natrix! Lots to like here. I particularly enjoyed 7a, 12a, 24a, 3d, 4d, 21d among others. I’m on a train at present, so made for a better journey. Will have to wait until I get home to see if there are any more detailed discussion points to raise. If so will put in reply. If not, just thanks and welcome again!

Thank you, a smooth solve except 25a, which came to me after I'd slept on it. Liked 12a, 24a, 20d, 21d, 16d, amongst others.
