Lovely spacious mix Luc ,I like it a lot.
I'm finding this one a challenge with the drum tracks with phase issues and maybe comb filtering especially with the kick and snare.
Listening in mono on the Auratone sounds nice and punchy in the bottom end,as a personal preference a touch too much reverb in the vocals.
When listening in stereo the bass and kick sound a touch spread out loosing some definition and punch,maybe too much due to too much bottom end of the bass and kick in the side channels ?
I found getting in the habit of alternating from stereo to mono and using a mid side plug inn with the centre channel removed to hear what's happening in the she side channels and side channel removed to hear what's happening in the centre is a great tool especially on headphones.
Good Job
