this is my tile for challenge nr 19 (find it here ). I agree ,i could have colored the black more even . But i wanted to give this a try and I like this technique. Below the very first try-out in my recycled sketchbook:I used a thicker pen to fill the black .
I was not sure if I should put this up but then i decided i would because this is the beginning and not the end.It certainly is up for more exploration .
