I just found out about a great initiative from artist Jake Parker - mrjakeparker.com - called Inktober! It started as a personal challenge to himself and has become a way to encourage other artists to further their inking skills. I haven't spent much time inking, to be honest I haven't created new art in quite awhile. So, even though October is almost done, I thought this challenge would be good for me.
Here's some old inking I did years ago.
