In class we are no longer working on our Rembrandt-like study. However, I took a picture of the painting so that I could continue it.
I was not entirely happy with the under-painting for this particular portrait, so I made some corrections, particularly with the shirt and the hands with opaque paint.
In doing that I liked the figure much better. However, I lost some of the transparency from glazing. For instance, the head now looks like a cardboard cutout. After the paint dries, I plan to move in with some glazes, to see if I can get that homogeneous look and feel again.
