Hi Julie,
I think you're really close to being finished, and it's looking good! I especially like the little mouth.
I sometimes use tracing paper to get an exact size outline of the features and hold it or tape it over the painting to check proportions. It's a helpful thing to do as long as you're reasonably sure your photo reference is not too distorted. Our human eyes see so much differently than cameras. However, a more "high tech" way to check your work is to "draw" an outline on the computer over the face, and print it out the exact size of the head in the painting, but on inkjet transparency film. That way you don't have the "cloudiness" of the tracing paper. See the example below. You can achieve the same thing with a Sharpie marker and transparency film as long as your photo head is the same size as the painting head. The only problem is trying not to overwork the painting with excess detail, unless that is your goal.
That said, I think the right eyelid needs to come down a little at the upper lash line. Do you like to add the highlight on the iris? I do. I think the eyes should have the most detail on the face. And this baby is all about the eyes - so cute!
Happy painting!
