Colorful digital portrait painting

Hello everyone, i am here to share a new digital portrait painting with you all.
i am really loving these colorful way of drawing portraits. although the display i am working on has a bit color difference so later i have to add a bit more saturation.
and after that the drawing looks much more colorful and vibrant.
another thing is that before i used to use a few colors within a very small range. but now i am trying to mix the colors associated with another color, and thats how i am trying to bring some color harmony in here.

here are some process shots:
