the musical side is OK, nothing more, nothing less.. it kinda goes on and on, there's no climax or super catchy moment... so even though it has a lot of variations, it still sounds a bit monotone to me.. if it's supposed to be some game backround music, then it's fine
at 1:04/4:11 there's some weird change in progression, not wrong, but it doesn't fit the happy rest of the song imo
and it could use more effects, you know, some whoosh every few bar
mix sounds quite clear, no major mistakes, keep it up :)
Nice! The synths are moody, and the transitions are smooth. The vocals are interesting. (I like it.) My only complain is that the mixing was a bit off at the beginning. Mixing is always up to you, though. Good job overall!
