They worked fantasticly on that kind of paper. Love how the gradiants worked :)
I used Touch Markers. They work the same as Copics, but only cost the half. I like them quite lot for traditional stuff. The highlights are done with white ink and white gouache.
I'll make some more of them, maybe a little series. But I'll have to wait untill I get some new markers. My girlfriend emptied the ones I used for them quite a bit :D
