Cryptic crossword No 3,541

Hi Puckle! I think this shows real promise, though various issues. 1) Minor: clues don't conventionally have full-stop at end. 2) Hard to assess without annotations explaining parse: e.g. 10a, not sure how you get DEN, but maybe I'm missing something. 3) An example of a nicely parsed clue is 8a. 4) An example of a more problematic clue is 22a: not convinced that "attacks" is a fair definition; and "seen" appears functionless, all words must have function (see also "the" in 15a). Thank you!
