Terrific! Lots of interesting fill and cluing. I love seeing Leonard Cohen anywhere, as an answer, or a clue. Bird on a Wire is a great song, but Suzanne has been in my top 5 all-time songs since time immemorial (which for me is not all that long, but still).
Well done! ETCHASKETCH/LUCKYCHARMS/COUGHINGFIT all crossing was fantastic. The pedant in me would argue that OLEOS should be clued differently, as mixtures would typically be a clue for OLIOS
