Pencils, outlines, markers, etc.  I'm pushing through with fully-colored pieces, even though I can't do the drawings all that well as it gives me a target for The Vision™.  This drawing had quite a bit wrong with it.  First off, I gave it a torso.  That's the quickest way for me to fail at the moment.  Next up, the head shape is wrong.  The eyes were screwy BEFORE I made that dilated pupil with the marker.
