Nice mix so far though you could go much harder on the sidechain ducking that you've got being triggered by the kit for this style
I couldn't tell if it's ducking more than just the pads.
I personally think you could high pass the aux vocal (lower pitch one) a bit higher, it's got more bottom end than the 'main' vox and sticks out a bit.
Or re-introduce some bottom end in the higher pitch part, if there's any to be had.
Also I'd use the vocal to sidechain compress the Vox FX channel, so that it pushes the FX out of the way, then lets it swell back
