Cryptic crossword No 2,603

Thanks Orinoco. I'm finally getting around to commenting. I thought this was a bit more polished than the last one of yours I attempted. I did have to reveal 18a, 1d, 11d, and 17d. Favs were 21a 3d, 5d13a, and 20a. Overall I liked the conciseness of your surfaces. More in reply.
