I was just going to do a light sketch, so I was using cheaper paper sketchbook... then I wanted to ink it, then I wanted to try color-ink on it. Since this paper was too thin for water it got so lumpy I had to stop in the middle of it and just smeared some color for the shirts and background (-o-;) Next time I will make sure to go back to my regular watercolor sketchbook.
This is what I consider very old-fashioned way of fanart coloring (this reminds me of my school buddy's fanarts from 20 years ago!), but I really like how sharply color ink comes out when need to. Definitely more versatile than watercolor pencils... I still love watercolor pencils but I can probably do a lot more with color ink. I love exploring on this medium.
