I did not know Amanda Palmer. Your sketch was enough to make me interested, and then I read @bryan-imhoff 's comment that she performed with Neil Gaiman, one of my favorite controversial comic creators. So, I go to youtube and open up the first result I get... and then I GOT SLAPPED IN THE FACE by Runs in the Family!!! What a great song, so powerful and intense and now I can see where the passion in your drawing comes from. You two make a great combination!
This is what I enjoy most about social media --- just by sharing a few positive experiences with an artist I sincerely enjoy --- more folks are turned on to the work of that artist.
