How to change a photograph to look more like a drawing

[denzjos]

What I did (a quick workflow) : 

Select the girl, copy the selection to a new layers and use 'color/levels/Auto Input Levels', Hue Chroma, Hue Saturation, 'Colours/Brightness-Contrast/Contrast' on the different layers and blend them with different opacity to own taste. The result is not realistic because the sun is low on the horizon, so the girl is in backlight and on a photo she should be dark. Now after little corrections, it look like a flash is used to lighten the girl.
