It's been a while since my last post bit i've been so busy doodling 😊.
This doodle jas been made with rotring isograph and radiograph pens. The 0.25 pen seems to have a little problem with the inkflow. After a few years of non-usage i guess they need a thorough cleening. There is also a big difference in the black pigment in this ink vs the sakura Pigma markers. The rotring is less intense. A positive point is the linewidth, this is much more accurate wit the rotring pen. This allows much finer work to be drawn.
