Tan Lines

Graphite on tan paper

It's December, yet the model's tan lines were as provocative as if she had been in the south of France a week ago. Yet, the lines were only on her back. Her front was devoid of lines of any sort. Perhaps a tanning bed, but why would one wear a suit in a tanning bed?  As I drew her, I wondered if she was aware of her graphic presentation? 

I'm new to drawing the figure since spring. I'm in a group setting, but without a teacher, so it's once again, seat of the pants kind of art — just like watercolor, acrylic, oil and pastel. Why should this be any different?
