Really nice pic/drawing. I love the rough style.
One of the things you might be careful of is putting things in because it's in the photo. Being selective is a good step in tracing or projecting. It's something I learned as an illustrator. Despite what people might think, that tracing is purely literal, it's not. There's an art to it that comes out in knowing what to put in, what to leave out, what to change, what to simplify and streamline etc.
I mean, it's all a fun ride, dancing lovingly over the features of someone you love, and that's a groovy process. But don't look at it like you're taking dictation from a source photo. Knowing how to draw comes in handy for this kind of process. So for example when we're doing pictures of glamorous women, they get streamlined in the face, where the nose is simplified, the eye make up and lips are often pushed and shadows are taken down to a few really specific and telling one and are placed for effect to emphasize those features that women themselves historically emphasize.
So when an artist who draws in those elements in freehand drawing to begin with, because it's how they would translate a lady's face, they will bring those sensibilities over to their drawings done from a projection or a trace. They go with what they know works for their aesthetic. Tracing only rarely teaches that. Drawing very often does. And experience and looking at how other people stylize their work is very important because it gives us ideas. And then we go and try them out and over time develop out own editing process and don't have to think all that much about every little detail. It's the classic "Big Picture" that we're frequently aiming for in a drawing.
I took your drawing and tried something out to see if I was right, because that cheek shadow you have to the left of the nose and mouth didn't make sense to me and I could only guess it must have been really prominent in the photo for you to put it in. So I minimized it and to my eye it looked better. The problem with that is that I don't know what your daughter looks like. And in portraiture sometimes it's those things that make the likeness resemble them more.
But you had said that your daughter's likeness was historically elusive to you. Aside from being able to paint and draw people we're close to is tough for most people, we're almost feeling like we're insulting them by changing something. . . even when it makes it a better drawing. None the less, on a separate version, you may want to erase back that cheeky bit. . . unless you're saying she's cheeky, in which case it's funny and revealing. 
Let the viewer's mind complete that bit. It's perhaps a little overly descriptive. Let the mind run with some of it and as such the viewer is actually more engaged.
Anyway, it's a sweet drawing. And I like the coarse style for a girl. The contrast says 'tomboy'.
