I wouldn't take anything you say the wrong way as I know you'll have thought things through first.
I will be bouncing colours from one object to another, but at the moment I'm trying to keep them clean. I've made too many errors in the past by trying to unify too early. The dark wash is just a layer on the top and I'll work a fair bit before I've finished. Her skin is full of different colours already with orange, green and blue fighting it out in there. I was hoping that you'd see that her left side of her face was slightly scrunched up as she's sleeping. From the picture I've posted below (a close up) her nose needs a bit more moulding. Have you ever watched your children sleeping and seen just one corner of the mouth rise in a smile? That is what I'm going for in the face. I lowered the left eye a fair bit from the beginning to bring it into line, now you're going to make me think again - rats!
For the composition, there are additional elements to bring in that will make it more balanced. The points I'll look at and consider, as I do with every comment.
