"M in Profile", Part 2

I've been a little negligent posting updates for this paintings progress. To make up I'm going to put up all the stages I've yet to post in this one update. It's the second pass on the Red Umber underpainting then the transition to color. I also made some composition adjustments and an additional hair piece. I plan to also add some sort of collar element:

1st pass. Lead White & Burnt Umber Warm.

2nd pass. Lead White & Burnt Umber Warm.

3rd pass. Full color.

4th pass. Full color.

4th pass. Full color.

As you can see in the last two photos I prefer to leave the hair at a rudimentary stage until I'm farther along with the skin that way I can work back into the skin with transparent hair edged. The skin is about 90% done and I'm sure I'll see more things to tweek as I bring other areas into further completion. Some of the subtle overall color differences have more to do with the photos than differences in the stages. I don't think I'll do an underpainting like this again. I prefer an ebauche style wash-in. However, I'm very happy with my mediums. For this painting I'm using:

Plain old Lineseed Oil!

For oiling out and to add transparency to colors I'm using Oleogel from Natural Pigments.
