The intro has a light and bouncy feel to it, even with some of the darker undertones (yay Halloween). Has a Nightmare Before Christmas feel to it. I'm super happy with the 0:40 section, especially when the choir comes in. Brings about a buttload of nostalgia for me. Firstly Sinbad of the Seven Seas comes to mind, and then secondly it unlocked a deep memory from the sad scene from Bambi. I haven't had a nostalgia nugget that deep before, and it took quite a while to find. Aside from that, I really like how you've utilized the choir. 1:30 is a nice soft dynamic contrast to the song, and I'm really pleased with the brass at 1:43. Again, you've managed to make a warm and large space with your sound in this song, which I think does a good job at conveying emotional atmosphere too.
There's good bits of composition that I like. There's a type of call and response with the 0:10 section called by the 0:24 section (it's probably more of a reprise). It's also the main hook that you use to explore in every section. As I've mentioned earlier, a healthy amount of dynamic contrast. The drawn out soaring feel of the 2:40 section compared to the hurried composition of the first third of the song. Neat theme, and good execution IMO. I have no problems with the production either. Even with reference tracks, it still sounded authentic for me. I personally would boost the percussion a little more and maybe tone down the reverb on some of the low register instruments.
