Commissioned Portrait - Little Girls with Pearls, part IV

I had a good day's work, but I was so concentrated that I forgot to take progress shots. For this portrait, I'm using a black & white photograph to do a coloured portrait, so it's a little more tricky to convert the tones to tints. I also want to make sure, the two portraits have a similar background so 'Little boy with bow tie' is close by. Much more to do.
