The dark lines in your example are a great demonstration to show the effect, but they make that sunflower look like a scare picture for a poster on the disastrous effects of air pollution. Also, I look at that photo and wonder if the contour effect could be applied just to the flower. I can see how to do that with a combination of GIMP to isolate the flower one way or another and Inkscape for the filter, then paste the altered flower back into the (blurred) landscape. Or, just blur the landscape to obscure the contours and emphasize the flower. But again, that's back in GIMP.
By changing to a contour tone in the same color range as the flower, I suspect the flower's beauty could be enhanced, and a painterly effect obtained.
