Portraits from the drawing group

My art guild has a Saturday morning figure drawing "class" -- it's not a class, there's no instructor. We begin with 5, then 10 minute poses which I usually do on newsprint paper. After that are two 15 minute poses which I do on charcoal drawing paper and finally three 25 minute poses which I either do in charcoal or in watercolor. When I do the watercolors I do not draw, but just used the color to block in the areas of color and value. Here's a selection from last week.
