Mindblowing
I just love how this song keeps getting better, bigger, and deeper. My favorite part starts from 1:51, with a great harmony of piano, string, brass, and choir. It's really impressing to me. I absolutely love cinematic vibes.
But I think low key keyboards at 00:33 would've been better if it was softer(I legit thought you just brought a random piano plugin with default setting in a VST software). And i think adding more details(such as bells) would be great also!
Never played ArcheAge before, but I think you made a good cover from it. I hope she also likes it, too!
