I wish I could help. Most of the pictures I draw are from my own photographs or from pictures given to me for a commissioned piece where the person is already paying me to draw them a picture.
I personally think the price depends on the size and detail of the piece. I don't believe it matters what medium you use...it's the amount of work you put in it. I have gotten anywhere from a hundred bucks for an 18x24 commissioned graphite drawing to 45 bucks (which I asked less but the woman paid me more) for a small 9x12 graphite drawing.
Hopefully somebody here will have a better answer for you.
