It would be helpful to know what you want it to look like. What kind of realism are you going for? What is your goal? It is hard to give direction to a unspecified destination.
Johnboy covered it well. I don't really have much to add.
I'm not going for realism at all. I don't want my drawings to look exactly like what they are supposed to be. All my drawings have symbolic meanings that go much deeper than the paper. Art isn't just creating peices that look exactly like what you are trying to copy, represent, or imagine. It's so much more than that. I get these thoughts in my head, and instead of writing it down into words. I write it as lines, as a picture.
That sounds horribly cliche, but that's just how it is. My goal? The only reason I draw is to express myself. But I've allways wanted people to see my drawings for more than what they appear.
