two little sisters step by step oil painting

I finally added some color to the black and white portrait of the two little sisters by Bouguereaux.
Just the first color layer and it has to dry before I can add some more color. The white of the flake and titiaan  white paint lights up a bit but that will vanish when I add some fleshcolors (I hope) And of course a lot of detail has to be added too. Still a long way to go.
Here you can see some of the steps of the painting process.

I took the time to let the layers dry thouroughly and the last couple of days I started to paint again at this painting. Still...................... of course I am struggling at different parts and therefor there is a lot to be done. And again I have to let it dry before I can go on. So here are the different stages sofar.
