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.
The rule of Internet debate is that, all else being equal, the poster with the most available time wins.
