Thanks for the nice comments re: rocker girl!
Sherry asked how I created the sketch... I work in Corel Painter for this type of sketch. Sometimes I continue to work digitally and will finish the piece all in Painter (with color tweaking in Photoshop). Other times, I print the sketch onto watercolor paper (140 lb) hot press or soft press, paint it, scan it into the computer; and work over the top of it in Painter (dry media like artist pastel) to get it just how I want it.
I will be finishing rock-n-roll girl in Painter.
