Real atmospheric, good tone for a loading screen. I like what you did with the percussion, like its coming from within a container, and it's slowly being released.
The brass was a great touch, but I feel like the strings may have overpowered the mood as it went on. Maybe they were too clean for my liking, perhaps maybe throw them into a feedback loop and turn them into something similar to a glitching noise, or make them more synthetic because I feel like it transitioned from R6 to Ghost Recon.
