Yeah like said before, the cymbals are cained but are pushed reeallly far back so they are kinda just adding noise,
speaking of noise there was some right at the beginning before the music, I'm gonna guess guitar amp? may wanna sort that.
sort out timing issues, (retrack, editing job?)
synth sounds a bit forward, reverb/lowpass? or just turn the fucker down
you seem to have the lowmid overwhelming guitar thing going on, eq those guitars or turn em down they are far too present imo.
I actually liked the solo tone, just sort some automation for it easily get's lost in the mix afterwards
I'm new to mixing metal (not new to metal) so I may be well off but these are just things I would change if it was my mix,
well done though
