i would say
1 , make sure your performance was on point
2 , was you standing in the best place whilst recording ?
3 , did you record at a good level ?
4 , is there anything in your recording you don`t want ?( EQ )( cutting out pops and clips and back noise that should not be there ie a police siren outside .
5 , are the levels of your recording going up and down ? quiet parts and loud parts making your recording sound uneven( compression )
6 , check timing issues if any
7 , is there anything you would like to bring out more in your recording ? presence warmth etc( EQ )
8 , do you want to add a bit more life to your recording ? ( effects ) ( layer your vocals with more vocal recordings )
these are things you need to ask yourself , then make the changes .
