Not yet done :P
Assuming this is still a WIP(Work in progress) I think it's quite calm and nice. This also seems to be something different from your other works ("DangerZone" and "I Remain"), which actually feels like a new fresh breeze of air.
I consider this to be a type of soft-rock, but since we don't really have that section, I guess general -rock will have to do.
I would like to make a recommendation to your co-worker, a few songs made by a member of this community called Kayoszx. His heavy-metal instrumentals are definitely more heavier than this, but iirc he also has a lot of ambient songs (though I really think that his heavy-metal / soft-rock instrumentals are nice enough).
5/5 - I am going to be honest, general rock is not my "thing", so I really don't know how to rate it. But since I made the comment, I might as well give it a score. I also find this promising, so 5/5 on this section can actually fit nicely.
9/10 - I heard better WIP's, but this is not that bad :D
