Here's a drawing of Hatsune Miku that I messed up pretty badly:

I'm pretty sure that I shouldn't have made her pupils solid black, but what else did I do wrong? Is there anything I can do to save it? Would making other lines bolder help to reduce the contrast of the eyes with the rest of the drawing? Also, I could take some lines out digitally, like the line starting at her chin that moves up below her left eye (it's supposed to indicate a shadow).
Here's the pencil drawing, which looks nicer:

As you can see I used reference points galore in order to draw this.
Here's the image that I was copying:

At this moment in the video Miku's smile (her entire face, not just the mouth) is contagious. I couldn't quite replicate it, not even in the pencil drawing.
Some final thoughts: If you're going to ink your drawing, don't follow your pencil drawing too closely, because what looks good in pencil may not necessarily look good with dark ink over it. Also, inking in a sketchbook is starting to seem like a bad idea because there's no place to rest my wrist when working close to the edge of the sketchbook. I've gotta start ripping the paper out of the sketchbook first, and I need to get a desk.
