Like most paintings they are created in "layers" and in "stages". Bob calls this part a "resting" stage where you let the image settle and start looking at it from all angles, checking the values (which are way too much the same in the circus one) and light source (WHAT light source?) The wonderful part of working in acrylics, of course, is that you can go back as many times as you want, adding and subtracting.
We had our wonderful Puerto Rican model/dancer again today and she had all kinds of poses for us.
In additions we had lessons on varnishing your work (that is what Bob is doing in the last photo). And on fixing mud (which we all mix up from time to time). We got some excellent recommendations on art books to read.
