When it gets down to the very end and I need to double check the features to zero in the likeness, I get my calipers and bump the lines around as necessary. A mm here or there can make all the difference. I think you did quite well.
I love what you have done with the face and arms and the hands are very good. Everything Rob said is right but I came back for another look because it is so pretty. I have a couple things you can work on if you want to. In the mass of blueberries, paint one or two a little more distinctly. In the grass, it should be a more uniform color with just a few blades defined well enough to indicate grass, especially around the girl where they will be bent. You will have to experiment with value to find the one that sends it into the background. Last, I suggest the basket should stand taller than the girl's hand to add depth. You could also add more depth and send the grass into the background with some value changes from dark to light where the dress meets the grass and then rolls around the body. I hope this is the kind of feedback you wanted.
