Hi,
I think the mix is good.
What I’d consider is removing the tremolo (or at least decreasing the depth) on the pad in the intro. For me it’s too pulsating. And a shorter intro in general can’t hurt (let’s say the whole track could start from 0:16 right as it is now). Still in the intro, those subtle sound effects hard panned left are a bit disturbing, I’d remove those completely.
Cheers!
