The smaller lines line on her face (the blushing cheeks, the detail lines on her clothes that are shading lines, not outlines) you could mimic a little better by using a smaller brush, or by cheating and lightening the color from black to a grey.
You said you used a size 2, so you may have to raise the resolution in order to do it, if you use the smaller brush method.
Your quality would also have been higher if you did the trace with a higher resolution, you wouldn't see any pixel jags.
Other than that, you did as good a job as anyone could hope for.
I see in the navigator window that you only used a bit of your canvas. You could flip the canvas, then flip the image too, so that you have the image be horizontal. Then you could size it up. But I'm not sure it would look good, it might just make it look more pixelated.
Anyway, I'm going to assume it took you a long time to do this, so you might just want to be happy with what you have done, and try these tips for next time.
