@ Mahvin
sorry for the late reply somehow i missed your question before
Process was very simple
1 i duplicate the original (posting now )
2 used gmic Ink Wash (it is in Black & White menu)
3 changed "Ink wash" layer mode to hard light
4 scaled down the image
about 4 if you apply the filter to a large image and you scale down at the end(let say of 50), the result will be quite different than of the same filter applied to a already scaled down version,
Result may be more smooth but also more neat (before scaling down is often better apply a slight gaussian blur , that weird as may sound give a more sharp scaled down version,)
But then even more important start from a beautiful original as this from babasteve ( on flickr has a amazing Gallery with excellent panorama and portrait from all over the planet)
