Charlie, thank you for your comments! “Contrast is king”, I will copy that one in my little “learning” book where I also have the Doodlewash manifesto:) Thank you for confirming that it is “ok” to have some watercolour in a drawing. I do need to learn how to give nuances with the ink. I use Uni pin fine liner 0.3, 0.5 and 0.8. I think that I could need a 0.1 too.
