Hello, overall it's a good mix. I have 2 main things that bother me : The backing vocal (it's very boxy and hard to discern). The snare drum : it's boxy and the impacts dont realy translate through the mix, which is I guess the reason why you've put it that loud.

The rest of what i could say is more a matter of taste : I would have processed the main vocal more (reverbs etc.. ) and put it less loud. I would probably have glued the whole mix more too, but again It's more a matter of taste.

I hope I helped :)

Yes, totally accept. I just hear the boxiness when i checked by my headphones after finished. In the studio it's not. Thanks you so much.

I would have panned the backing vocals more (assuming there's more than one layer?).
I also don't hear as much low-end on the bass as I would like, but I am a bass player so I could be biased here!
