I first attempted Inktober in 2015. The experience was so fulfilling that I just had to attempt it this year as well.
I doodle from experience, memory, observations and imagination. At the end, it forms a mind map of sorts, of every thought my mind went through.
Material: Micron pen, Koi brush pen, black ink, paint brush, paper.
