Puzzle #151: Freeform Freestyle 11

To wrap up the freeform freestyle series, we've got a big 21x21 grid (pdf, puz, pdf solution). Fear not - to make up for the extra size, I've pitched the cluing easier than the 15x15 freeform freestyles. By the way, I haven't been mentioning this in every post, but Brooke tested this one, as she's tested every puzzle in this series, and her feedback has been invaluable. Happy solving!
