Well, I do not hear any background noises nor room ambivalence that could disturb other instruments.
 
So on a technical level I'd say the quality is good.
 
Now as others have said in the context of the music it's hard to say what trouble you have with it in the mix. If the song is bass heavy you may need to cut some of the lows in the vocal track or add some sparkle on the high end.
 
Maybe you could post your current mix (as is) and then some better advice could be given.
