Nice arrangement.
The vocal seems a little distant or disembodied.
Did you throw a heavy high pass filter on it as there seems no lower mids or bottom end on the voices?
It's even more so when the heavy drum beat comes in and takes up so much of the bottom end - especially in the chorus, (sounds like the vocals are next door and the drum kit is in the listening room.
