Experimenting with acrylic and oil pastel

While vigorously neglecting my lawn and yard this weekend, I have been experimenting with acrylics and oil pastels. So far, I think my painting is a bit derivative of others whose paintings I gravitate toward, but I am just letting it flow and seeing what happens. I am hoping that if I can paint one or two a week (and more when time allows), a style will emerge that is all my own. These two are a combination of acrylics, oil pastels, and rubber stamps for texture.

I am also experimenting with different facial shapes and trying to improve my shading and general brush skills. It does not come easily for me, which is good. If I catch on too quickly, I tend to undervalue the skill and lose interest.
