I love it! I've never heard Spooky elevator music, and this is peak!

Hey there, so I have a little bit of feedback for you. My two cents.

The first piece is that I think the overall balance of the instruments could be improved on. Right now the piano sounds almost muted and the xylophone (bells? whichever that higher pitched instrument is) seems quite bright to my ears. And it all feels a little cluttered in the middle which makes it difficult to hear the different elements of the track. Making another effort at balancing I think will help mitigate some of these issues. Adjusting their respective volume, EQ, or panning the instruments away from each other is probably where I'd suggest to start.

I'd also suggest a little more reverb and delay overall to help fill out that otherwise empty space.

Thanks for sharing what you've made, hopefully you continue to improve what you have and keep up the good work :)
