This time I remembered the transparency! More experimenting in GIMP, this time added some smudging along with the lasso. I screwed up her proportions and her anatomy is off, but oh well. Her legs are too short! Lesson learned: use a much bigger palette and learn to scale correctly. I won't be using that smudge tool again. Ever.
