Reduce to 10 colours in the best way

can be that 10 colours is a little too "ambitiøs" - but the thing is: Some parts of the picture matters more than other part - The face has a high priority, the body -> a lower, - and the backgruond -> very low - if you understand

(Maybe I'm really asking more about how I come from the image to a more simple painting / drawing / cartoon (there could be a more direct way than starting to reduce the colours))

The idea is to heavily blur the background, then blur the body a bit less, and not blur the face (or not too much). The Median blur is often better than the Gaussian because it keeps the edges.
