Off to a flying start with the challenge, here's day 1's submission.
Drawn with a Moonman M2 filled with Waterman Harmonious Green ink, I'm not sure the colour really works for the subject but I wanted to try a range of pens and inks over the course of the challenge.
The paper was a bit of a struggle too - I used a watercolour paper that is probably a bit too soft and a bit too textured for a fine-nibbed fountain pen.
