Well, I set aside "Knowledge is Power" for a few days because the face was giving me fits. I'll get back to it soon, but in the meantime, I'll share the illustration of a role play I'm doing on Tumblr that I did while shelving the other piece. (Edited to upload a version with some corrections. Oh, and OMG, I completely spaced on giving reference/brush credit when I posted this here.
Faestock for the female figure reference and
Project-GimpBC for the grass brush)
