Yeah, I could of added a white contour while I was doing the drawing, but the black outline does make it pop-out abit. I should add whites on the bottom of the ear, where it's resting and also on the hand under the other ear, so it doesn't blend with the background and body.
Thank for the comment, its my actual my first drawing using conte, so when I got the drawing back from the teacher after he grade it, I've framed it.
