My thoughts:
Well done for submitting! Unfortunately, in this case there are no FX for me to rate on, only music, and I'll do my best.
The short synthwavey loop you've shared here is melancholic and gives off an air of dread -- good feeling, but to me, it feels a touch bland emotionally. Also, hearing this on repeat on a (presumably) long RTS level might be difficult. The idea is solid, but could use some variation.
