Overall this is a nice song and very original in the lyrics and I like the subject matter, which is pretty universal in appeal, and the melody. I understand it is a demo most likely.
However, the Instrumentals lack crescendos and decrescendos and feeling/variety. Perhaps use more live instruments and less synth...? Also the lead vocalist has some pretty strong pitch and other (support) issues: for example it's sung all the same, lackluster and lacking feeling and losing pitch on almost every phrase. You could correct some of this with Melodyne and by adding ups and downs to the phrasing with volume controls (volume increases and gradual decreases) on your Protools/Production and or mix. She needs to sing this with more feeling!: Happiness and warmth in her voice and picture what she's singing on every phrase so she doesn't always sound the same and flat. Anyways, I'm a vocalist so I'm super picky :) All the best to you in 2019!!! Good job, good song. I hope it does well for you.
Wonderful, like usual!
Marry Christmas and a very Happy New Year!
