I worked on these two 5x5s a bit today...see, I did cloth them! Ha! I often sketch in my figures in the buff simply because it is easier to get the form right if I don't worry about clothes! Once I'm happy with how the bodies are looking, then I can decide how to dress them.
....and another short session and they are starting to take shape. I will have to go back over the backgrounds - they are just blocked in and need detailing yet. Long ways to go still.
