Sincere question here, do any of you have difficulty seeing or understanding details in the sketchier pictures?
Yes. It also makes response a little difficult because it's very unclear what's a mistake and what's a temporary artifact of the sketching progress.
I recently got addicted to sketches and wound up making a unilateral decision to ink everything I did just to get me out of the habit. Been really paying off as far as arting goes, check my recent gallery.
