Character: An Instrument muss communicate feelings! The right gear used in the right place provides a track with the necessary life.

EQing: The bass carries a piece and provides warmth - it should not take a back seat. Whereas highs can dominate the sound in an unpleasant way quite quickly. They are better brought forward by the appropriate EQs in mastering.

Space: Digital reverbs serve as effects. Natural sounding spatiality is finally provided by analogue reverbs, such as a gently added EMT plate reverb.

Time: An important factor. Without time, no good results. I take myself the time to work on a mix until I feel that it has ripened.
