Likewise I was slow at the start, but once I got the long ones it was very enjoyable. I guessed 14a was a rhyme of 17a, which helped
I agree with the comments on 2d, 6d and 21a. I'm also not sure if I've parsed 19d correctly
I enjoyed 1a as I know the area, but I did like the twist in 20d, so that's my COD too
