Inktober  is a social media initiative created by Jake Parker where artists challenge themselves to do an ink drawing each day throughout the month of October.  I first started participating in the challenge in 2015 and have been participating ever since. Each year helps me practice my illustration, come up with new concepts and sometimes even new characters that appear again in other projects. Here's a couple of my favorite ones from the past years.
