i would karma you fallie but i ran out of karmas to give! >_<
to karl, erm, haha, to be honest i have no idea how i ended up drawing the way i do. some people have it easier at capturing the likeliness of a person than others, even when the representation is not at all realistic or accurate. but you can always achieve a super realistic representation of someone by being very precise in the placement of their prominent features. to do that you have to train your eyes to calculate the space in between everything. personally, being super accurate isnt my priority. i think the rendering of shading and lines is what gives the drawing a "professional/practiced" look and the way you do your strokes give you character that differs you from other artists. now i feel more confident in shading/lines, i would strive for more accuracy. but it is one thing i tend to fall down on...probably because i suck at math, haha.
