All my Inktober sketches were done using a Pilot Precise V5 extra fine on a handmade cotton rag paper. This paper is not optimal for drawing, since it doesn't hold up to eraser, but that also forced me to accept mistakes and think more about what I was drawing as I drew it. References for many of these were pulled from photos on an app called Sktchy, which is a great little artistic community that I recommend joining if you want some practice w/reference photos. Unfortunately, because this is an app, I can't easily link to my references.
I've done some minor editing to clean up the paper texture and remove minor stray lines, but I've tried to keep the character of the sketch intact as much as possible.
I love this one, and I know how hard it is to erase on that paper. I like that you mostly sketched the piece with no holds bar. I like taking that risk. I like that you did because I can see all your natural marks, which shows me more of your voice in the drawing.
I hope you post more art when you can. You rock.
