I've had this KO for almost 2 years now and was always going to mod his face to be like the comic sand cartoons but recently got one of those Gundam panel liners so thought I'd try it out on him 1st. Used to just brush on tamiya acrylic smoke thinned down but now see what all the fuss is about with this pens! So much happier with him now even Duros? (Think that's his name) got a make over. Plus a bit of chrome and gunmetal grey for good measure.
