I think it looks beautiful
The only thing I might say, besides the palettes which I will address in a moment, is the bring the boots up a bit higher. Right now they are ending, technically, right at the top of her feet. By making the top a bit higher, it'll look more natural.
On the topics of palettes, might I suggest making your own? That way you can play around with the colours yourself. Its rather easy to do in Paint(not sure about any other program). All you have to do is go to "Edit Colours" then use the huge spectrum to pick out a general colour area. Then, when you pick out your darkest or lightest colour, go by 5s, 7s, 10s, or whatever you choose to do with the "Lum" section. When you reach the end of your interval, you just click "Add to Custom Colours". It doesn't save them there, but if you put your palette next to your doll it should work out just fine.
If that doesn't make sense, I could toss up an image to show you what I mean.
